And I'm really not surprised.
From random friend requests to a slew of invitations to play farming games, Facebook is getting to be more trouble than it's worth.
Yes, I'm still on Facebook, but I don't use it nearly as much as I have in the past. And it's mostly because of how the social network has evolved and what people do on it.
Perception is reality: Facebook can't just exist, it needs to be liked. The experience of being on Facebook needs to be enjoyable. There is no law that says established social networking sites must always stay in business, forever. Consider MySpace, for instance. What users think of Facebook is, therefore, crucial.
