While I didn't invesitage chatroulette for this assignment, I have done with a few friends. Some of them decided it would be really funny to do it at the union...pretty soon everyone thought we were watching a porno or something...so I've never ventured into the world of chatroulette ever since then.
I have never had a myspace, so I just checked it out to see what it was all about. It's very different from facebook and I most definitely prefer facebook to myspace. I've also never heard positive things about myspace. Especially in the sense that there are a lot of "creepers" out there.
