A couple of months ago, Facebook released the Open Stream API, a new set of Facebook Platform APIs that enable developers to access and publish to the Facebook stream from anywhere. Since then, we’ve seen a number of interesting desktop client integrations, like the recent updates from Seesmic and TweetDeck.

However, a simple new website built on Facebook Connect, Flutteerr, illustrates ways developers could build websites that integrate the stream as well. Developed by Facebook employee Naitik Shah using the standard APIs in his personal time, Flutteerr currently only contains the Facebook stream (and resembles Twitter quite a bit), but it could be enhanced with a variety of features to make publishing to or reading your Facebook stream more powerful.

On Flutteerr, users can filter the News Feed the same way they can inside Facebook, including by Friend List, Network, Page, and particular applications. Status updates, comments, and likes are automatically posted to Facebook. However, you can’t share links, photos, etc. in the media-rich way that the Facebook.com Publisher allows you to.

Since the site is a personal project, it’s unclear what will happen with it going forward (though the name is reminiscent of this parody video from Slate called Flutter: The New Twitter). Nevertheless, the site does go to show what’s possible with the API.
