Cliqset is a Florida-based technology startup that end-users have had a hard time understanding. The company just released a new product that developers should have no trouble with at all and that could send waves of innovation across the social web. Called Cliqset FeedProxy , the service consumes user activity feeds from more than 70 online services like Twitter, WordPress, Tumblr, Last.fm, Yelp and LibraryThing and then produces an outbound feed that’s compliant with the ActivityStreams standard format. Sponsor That means activities from all those services can be read in a common language and 3rd party services can slice and dice them to create new user experiences. Several high-profile applications have already begun consuming activity feeds republished through Cliqset and the company says many more consumers are in the works. The most common analogy for explaining the impact of data standards is the history of the railroads in the US. When all the railroad networks adopted a standard size of track, then transport companies could carry goods cross-country over multiple rail networks. That opened up a new world of commerce. ActivityStreams is an Atom feed standard under development by many social web companies large and small. It aims to normalize the language that user activities are expressed in across multiple social networks. It’s intended to facilitate interoperability and cross-network delivery of user activity payloads. It’s important, exciting and inspiring work. Non-standardized activity feed publishing is like creating a high-way that only one brand of car can drive on, with one proscribed type of journey in mind. Standardized feed publishing provides a platform for a world of open innovation. This API enables user data to pass freely from one network to another or through multiple applications, unhindered by network-specific markup and namespaces. Facebook, MySpace, Netflix and other services are already making user data available in ActivityStreams format, but there are far more social networks that don’t. As we explained in the ReadWriteWeb research report The Real-Time Web and its Future : An extension of the Atom feed format, the spec explains it like this: “An activity is a description of an action that was performed (the verb) at some instant in time by some actor (the subject), usually on some social object (the object). An activity feed is a feed of such activities.” In the current draft spec, you can perform such actions as Post, Share, Save, Mark as Favorite, Play, Start Following, Make Friend, Join and Tag Object. An Object could be an Article, Blog Entry, Note, File, Photo, Photo Album, Playlist, Video, Audio, Bookmark, Person, Group, Place or Comment. These actions can have such contexts as Location, Mood and Annotation. Stream aggregator Cliqset publishes Activity Streams feeds that don’t require API authentication to view. You can see a sample one at: http://cliqset.com/feed/atom?uid=dbounds. The aim of Activity Streams is to have multiple social networks use a common language and have a common understanding of what all those things mean, so that messages can be read across different networking sites. Now the Cliqset FeedProxy tool will normalize feeds from more than 70 other services into new feeds in the ActivityStreams format. It may just be an initial inroad to interoperability between these networks, provided by a 3rd party and not yet extensively used – but it’s an important step none the less. What does this mean? It means that applications developers could build interfaces to display books read, music listened to, reviews written and more across multiple different services with as much ease as they can display standard RSS or Atom feeds today. It’s a powerful new level of granularity. Social media center Boxee and a Sun Microsystems community product currently consume activity feeds. Cliqset says many more projects are in development now. As the ActivityStreams community builds out more sophistication in the standard, there may be things like cross-site reputation included in such feeds. Cliqset has done a valuable service creating these normalized feeds for developers, but the obvious downside is the reliance on a middleman. Cliqset says it is talking to Superfeedr about creating some real-time feeds as well. That would be great, but would be another layer on top of existing publisher feeds. Perhaps if the developer community builds the kind of market-moving applications and features ActivityStreams advocates expect from the Cliqset feets, more publishers will begin publishing standardized feeds natively. While Cliqset has put a lot of work into normalizing numerous network feeds, the idea behind standards is that they can facilitate technical integration between parties with no prior knowledge of each other. Either way, Cliqset is putting the ActivityStreams agenda to the test. The company’s release could have some very significant consequences. Discuss

The Day The Highway Went Coast-to-Coast: 70+ SocNet Feeds Normalized by New API

Two years and a month after announcing that it would launch a more professional-looking developer platform than the wildly successful one at Facebook, LinkedIn today finally opened up a series of application programming interfaces for other companies to build on top of. Make no mistake about it, though – there’s some good news and there’s some bad news. LinkedIn holds an incredibly useful body of data about its users – not just because of the relatively high net worth it brags about its users having but because employment information is a very useful way to put a person in context on the web. That data is now available for an ecosystem of other developers to incorporate; TweetDeck, Posterous, Ribbit and several other applications already have. Sponsor The Good News It’s easy to get started. After two years of waiting, unreplied emails and heartbreak – developers should now be able to get an API key within minutes and start building on the LinkedIn platform. That’s great news and not something that could have been taken for granted. The API allows search. That’s great because with a little disambiguation done on the client side you can find the LinkedIn accounts of people you’re connected to on other networks. Unfortunately, no one is doing exactly that yet – but isn’t that the biggest value proposition here? I see a person on Twitter, on Facebook, on some other social network and I want to see what they do for a living. Let the app collect and expose that data from LinkedIn! Disambiguation of people with the same name and privacy limitations regarding who gets to see who’s information are both complicating factors. The coolest use of the search API we’ve seen so far is Salim Ishmael’s Knx.to . That service is limited to your own connections so far, but it’s definitely a keeper. The API uses OAuth . That means that 3rd parties can offer fast, secure, standardized authentication into your LinkedIn user account. That’s great. Activity updates are now parsable by type. The API allows developers to pull in just one type of the many updates a person gets on LinkedIn. Will someone please build an app that just shows me when my contacts change jobs and leaves out all the status messages, friend connections and other cruft? That kind of granular control has a lot of potential and is reminiscent of the vision behind the proposed user activity data protocol Activity Streams . And Now For the Bad News… The first use-cases make it look like LinkedIn is trying to be Twitter. Tweetdeck and Posterous are the most high-profile early adopters of the new API; Tweetdeck will give you a LinkedIn column (too bad LinkedIn contacts can’t be integrated into other columns) and Posterous will let you publish links to updates on that platform over to your LinkedIn contacts’ streams. Jobdash looks like Tweetdeck just for LinkedIn and job-hunting, but it doesn’t yet offer features like limited display of notifications by type – it’s just a big stream of updates. LinkedIn is not Twitter! LinkedIn’s Adam Nash told us this morning that he loves the Twitter and Twitter-like integrations but “integrating messaging isn’t the goal, there’s a wide range of business applications that will benefit from it. Twitter is hot so people are jumping to that but there are far more compelling business cases.” Two years after the business-oriented platform was announced tiny Tweetdeck was just so hot it out-maneuvered all the business applications that could have been built to showcase? I don’t buy it. Just like the formal partnership between Twitter and LinkedIn earlier this month , I worry that this API is built with marketing, promotion and broadcast functions best served. Terms and Conditions are unclear, restrictive and changing. The API terms say that you can’t build applications that compete with LinkedIn. API management service Mashery CEO Oren Michels (disclosure: RWW sponsor) had this in response to say: “It appears that you can’t create a new experience around LinkedIn, an iPhone app for example. You might create some interesting bolt-ons to other services that might drive users to linkedin.com – but that’s a very 5 years-ago approach to an API.” “The signal from this is that they aren’t encouraging developers to take the social graph and deep knowledge of peoples’ professional lives and create new UIs for interacting with LinkedIn because they are explicitly concerned about competition,” Michels said. “LinkedIn has amazing assets and a great business model – get out of the UI business!” Likewise several developers have expressed concern around the commercial limitations on the API. LinkedIn’s Nash clarified with us that those terms simply prohibit charing people extra money for access to the free LinkedIn service and building an advertising network on top of LinkedIn profile data because of privacy concerns. Finally, the terms of the API aren’t very clear. Nash said they were a work in progress and likely to be changed. Some of those changes appear to have been made in the 3 hours since the API launched . Likewise, Michels points out that rate limits on accessing the API aren’t made explicit – only that there will be rate limits and that a developer can email LinkedIn to request a personal expansion of their limit. Not playing nice with others: LinkedIn is exposing what it calls an Activity Stream, but it’s not at all related to the standardized format that Facebook, MySpace, Netflix and others are now publishing. LinkedIn publishes some Microformats but has been entirely absent from the wide-ranging community discussion of Activity Streams formats, we’re told. Michaels may have said it best: “There are some really smart people over there at LinkedIn. If this is what we waited 2 and a half years for, it’s a bit disappointing.” It is a bit, but not entirely disappointing. We look forward to seeing how the platform evolves and what kinds of applications are built on top of it. The web has been waiting a long time for a LinkedIn platform – now let’s see what happens.

LinkedIn Finally Opens Platform: The Good & Bad News

Twitter turned on its long-awaited Geolocation API today, meaning that users can opt-in to having their messages annotated with their exact locations. The significance of this is made clear by comparing it with last week’s release of 500 million time-stamped Twitter messages for analysis. “You take this data, mash it up with any other very large corpus of data with timestamps,” Flip Kroner of data marketplace Infochimps told us, “and you’ve got a web app.” Today’s announcement of the availability of location data means the same thing: you take this data, mash it up with any other data with location information and you’ve got an app. From Digg or StumbleUpon for your favorite coffee shop to political and disease tracking – there’s a whole lot that’s possible. Sponsor Exposing location data is an opt-in feature for users, but 3rd party app developers are being told to “encourage your users to enable it by sending them to their settings page.” Users will have to be both prompted and incentivized. Fortunately, a location-aware Twitter experience is something that will enable developers to deliver value to individual users immediately and in isolation – it doesn’t have to be one of those situations where “this will be cool once other people I know are using it.” With the announcement today of Twitter search results being added to Yahoo News searches, Twitter data is now being used by all three of the major search engines. (Google’s implementation is still forthcoming, but the deal is done.) It might be one of the big players, but it’s more likely to be small innovators that make creative use of the new location data. These are possible Twitter use cases, but the standardized Activity Streams spec that Facebook, MySpace, Netflix and others now support also includes a geolocation field – so if the walls around Twitter ever fall to interoperability then we could be seeing innovations like these across all kinds of networks. Here are some of the kinds of things we expect, or would like, to see. “Party Over Here” Bot: Automated Geo-Replies Want to know when you’re near a certain type of public event, great wine shops or deals at Macy’s? How about when friends, close friends or friends-of-friends are near? It’s not hard to imagine a bot that you subscribe to on Twitter, that then auto-subscribes to you, notices when you “check in” at a new location and automatically sends you a reply when whatever or whomever you’re interested in is near that location. How about a bot you can Tweet “@whereami” to and that @’s you back with a link or stats about the location you’re in: nearby restaurant reviews, notable landmarks, crime rates, apartments for rent. Talk about augmented reality! How about a bot you can Tweet “@whereami” to and that @’s you back with a link or stats about the location you’re in: nearby restaurant reviews, notable landmarks, crime rates, apartments for rent. Talk about augmented reality! There are all kinds of bots built on Twitter already, but one that can mash-up your physical location with its data store is going to be a lot more useful than a bot that tells you when a sensor noticed your plants need to be watered. These are the kinds of services that will incentivize Twitter users to expose their location data. Assuming a substantial number of people make that choice, here are a few other examples that come to mind. Articles Being Shared From This Coffee Shop Today Include… Imagine being the location-equivalent of Digg-submitter of your favorite coffee shop’s hottest online articles each day. Most Twitter search engines index not just the 140 characters in a message, but the text in links being shared as well. If you think people like being the Foursquare mayor of a popular coffee shop, imagine being the location-equivalent of Digg-submitter of your favorite coffee shop’s hottest online articles each day. Think people just stare at their computers in public these days? A service like this could shake that up. How about a StumbleUpon implementation that lets you stumble and read articles from people who’ve Tweeted from the same place you’re in. Imagine walking down the street and considering two competing coffee shops; what’s been on the reading list of each today? News at 11: Local Interest Survey Tool Think local TV news and newspaper companies would be interested in a stream of hot topics in their local area? They’d be foolish not to; what a great way to discover breaking local news to report on. Does your local newspaper print a selection of letters mailed in each week, but list the number of total letters received on the hottest topics of the week? Imagine capturing that local chatter from a much larger sampling of people. Local tweets plus an entity extraction algorithm. Cop Watcher Imagine taking a map of tweets discussing criminal activity, or police misconduct, in a city and comparing it with a map of the same from local police agencies. Some places that warrant more official attention could be exposed. Inventory Forecast If people in a certain city are twittering like fiends about a new product hitting the market, store orders, marketing and other parts of the supply chain could benefit from an earlier warning about it. Politics & Marketing People in Oregon are sharing a Huffington Post article about today’s health care reform announcement a lot? In Seattle, Washington perhaps not so much? Political organizers of a certain persuasion could find that information actionable. Want to know what news outlets are on the ascent with people of a certain political persuasion? Cross reference your shared links from users in a location and a map of political contributions for the last election. Want to know what news outlets are on the ascent with people of a certain political persuasion? Cross reference your shared links from users in a location and a map of political contributions for the last election. How about unearthing Twitter users posting about environmental issues who also live in areas with environmental issues that an organization is working on. Want to measure local effectiveness of marketing campaigns? Imagine Radian6 or ScoutLabs using the location API. That’s only a mater of time. Flu Trends+ Think Google’s use of search data to map out global disease trends is cool ? Why stop there? How about pro-active messages (via Twitter) when there’s an increase in messages about being sick in your area? Of course all of this will work better if more people are using Twitter and if people expose their location data, but that may very well happen. Prompting and individual incentives could be big drivers. The degree to which Twitter data is open for analysis by outside parties is a huge asset.
