Facebook opened up Open Graph tonight, its tool for letting third party developers share actions in your timeline. It announced 60 partners tonight, including AirBnB, Runkeeper, and Pintrest, and now it's open to developers everywhere. Basically, privacy is over.
The new Open Graph tool will let developers plug into Facebook's social graph to let users share actions they are taking on other sites. Right now, you can see that when, say, someone listens to a song on Spotify. But with 60 companies doing all kinds of different things, and now it being open to anyone, pretty much anything we do online is going to end up on Facebook. Yay?
