Hold on a sec - replacing facebook with something else is not that simple and i'd venture probably unlikely. there's a huge network effect that facebook has in place. it is not just for games. it is starting to drive traffic to various news outlets: (http://www.pcmag.com/article2/0,2817,2385095,00.asp http://www.pcmag.com/article2/0,2817,2385095,00.asp) and it is probably just getting started. There is something substantial to facebook that makes people come back. And naturally as a company is growing and adding more features, the API is going to change. I personally use it a lot to share news articles with my "friends", but the ability to now share those articles with only certain friends, directly from the news website - which hasn't been implemented everywhere yet, is pretty interesting and shows that facebook realizes that there are friends and there are "friends". It would be far easier to have disrupted something like Google, which doesn't have the same network effect as Facebook - but even that has been very challenging for anyone to do.
