I suspect that one of Facebook's problems is that people naturally overshoot with their social network and at some point you end up with "too many" friends and logging into Facebook reveals less interesting content and more noise. I know this has certainly happened to me. 80% of the content I see upon logging in is information from people that I couldn't care less about. Facebook has encouraged this from the start by avoiding support for stratifying friends into separate groups. It's worked well for them by simplifying things, but I think they'll begin to experience some natural attrition from it as time goes by - social networks just naturally grow and grow because you very rarely "unfriend" someone. At some point it becomes burdensome to check it instead of fun and then it's all over.
