I've never had an interest in getting a MySpace. Reading this thread, I have even less interest. Simply put, it doesn't sound like the place for me.
I feel compelled to chime in about Bebo, and totally agree with Laura's comments about it. I just wanted to say that if you Google the first and last name of someone you know, and they have a Bebo, you will find it right away, guaranteed - as I have many times. So, clearly poor security, even easier for predators to get in touch with somebody.
