I hated myspace because people were given too much freedom to muck up their pages. So if you visited it might not be legible because of background or text colors, there might be music that suddenly played but there was no common location to shut it off on each persons page, or it might just crash your browser cause they had too much flashing shit all over it.
Of course, when Facebook was out I remember saying "why do I need Facebook, I already have Myspace!"
And now I'm on Facebook and no longer use Myspace. I was also a late adopter to cell phones (but I'm not a big fan of being called, I'd rather email)
