To some
people, it's a place to meet new
people (as in, chat with
people that you will never meet). To others, it's one big scene contest. In reality, it's a mixture of both.
It's an addicting networking tool, used by kids in high school and college. The loser's flaunt the number of friends they have over other people. Even though nobody really cares, once they leave the house (if they do, that is.)
It is also a place for every band to make a profile, even if they don't have any
music to listen to.
