myspace good or bad for teens?

i have had a myspace for awhile and i have read and saw some of the things on myspace and they aren't all exactly what i would call good because i have saw/heard of some things that i personally wouldn't like if it was my child, but then there are times that you can catch up with older friends that you lost touch with, so i was juts wondering what you thought about it for teenagers, do you think that they should be able to have a myspace before 18 or not, good or bad? i would like to take this time to thank everyone that has taken time out of their day to come by and read my discussion and hopefully provide an answer for my discussion, i hope that you all have a great and happy weekend, thanks once again for taking the time to come by and happy mylotting!
