I don't get Facebook, explain please!

seriously it is not very intuitive, you cant really do much. no forum, no chat.

on myspace at least people have big profiles and can post stuff, on Facebook you first have to become friends.

i really dont get why this got so big!?

problem is it makes me feel trapped. like i cant find or do anything, it makes me want to get out of their.

and how do you find all the applications?

how the hell can some application on facebook be valued to 500K$/month whih i read somewhere.
