Numerous people have said that Facebook is like "a walled garden"; in that things do go in, but nothing comes out. It would appear that they made the first step last night in "coming out," as it were.
Nick O'Neill of AllFacebook is reporting today that, without much fanfare, Facebook integrated their platform with their API. What does this mean to you and me? It seems that your favorite applications could possibly start popping up on ordinary websites and blogs any day now.
Web apps will be able to use cookies to track the users when they are using the app in other places on the Internet. So, in theory, you could play a game on any site and your stats will still be tracked.
The whole point of this seems to be to allow Facebook members to finally leave the site proper. Users could now go about the Web, doing your own thing, but still be connected to their Facebook profiles.
