Kiern, perhaps you should be hating the people who are using the program for these popularity contests, whining and harassment. You can do it anywhere on the internet, and other places are just easily corrupted and abused as myspace is. You can't stop these people from doing these things, period.
I don't exactly what you get by whining, however. If you mean keep up with a blog, to express your thoughts and recieve constructive critisim on your life events, then I disagree fullheartily.
Myspace is a great way for me to talk to other people conviently, and share my ideas with other people. I can read their blogs, and know exactly what troubles them in less time than it would normally take. Sure, this isn't exactly healthy compared to sitting down with a person and asking them what ails them, but at 17 years old I don't always have that opportunity. Sometimes, there are people I can't dedicate my time to. I have school, work and other friends to keep up with, and juggling these important people around can be a hassle to say the least.
I can use myspace to talk to people that I would normally never ever meet in my life, and I believe I have become enlightened in a way because of it. While some people do indeed only add me because they see my profile picture, or hear from a friend about who I am, it doesn't outweigh the important things that myspace provides.
There's abuse of everything man creates.
Hate man, not the machine.
