MySpace - is there an age limit?

I've been wondering this ever since I set up a MySpace account last year. How old is too old for MySpace?

Is there an unwritten MySpace rule which says you need to be under __ years old to be a part of the 'community'?
Is it only for single people?

Quite a few of my friends have since jumped onto the MySpace bandwagon, so i don't feel like quite the loser I did when I first started... but if you browse MySpace.com, it's easy to see their target demographic.

So to those reading this, what do you think?
MySpace - only for single youngins or what?
