I use MySpace. I love it and I hate it:
I like making a few friends to a plenty of friends. I like to PM chatty thingies. You even can upload pics and let other comment on what they think of.
I hate strangers whom are off the base, perverts who acts like "nice" persons...blah...and junk mails I don't know what are they're thinking, and wanting to be added to your friend list but turn out to be a creep.
Overall, it's okay...I can't say the number between 1 and 10. So I might list it as 7 (okay), they need to improve the safety by preventing children under 14 from registrating and pretend to be "14." Jeez.
