I think it
can be creepy, but in my case, I have two pages. One is for my band (which is a separate MySpace Music page), which is really great, 'cause it includes a jukebox so people can check out your stuff, download songs (if you choose to allow them to do so), etc. It's driven a lot of traffic to our official site. The other is my personal page, which is very much like Friendster used to be, but I think it's set up much better. (It has a lot more features, etc.) And, interestingly enough, I've been contacted for a few gigs and auditions through that page, and even booked an indie film that way.
So, I guess it depends on why you have a MySpace. Some people are celebrities looking to connect with their fans (NOT me, I mean real celebrities), others are fans making a tribute page to their favorite artists, some are looking to date, some to make friends in a new city, some are creeps who just want cyber-sex. There's a great variety. It's a lot like life.
