I started wondering that as soon as I joined last year. The best I've come up with is that it's run by a mind-control alien. What is this urge we all have to be narrators of our own lives? FB is really funny sometimes, and it's just enough drama to be interesting. Lately, I'm on hubpages much more though, I feel more productive here. My FB time these days is minimal, and the whole idea of running an imaginary farm is lost on me. But you're right, it sucks you in, and drains your time.
