Actually prefer Facebook over myspace because its more structured and since it is more school based it has come in handy when trying to get ahold of people from classes that I might have missed. Also I like their no limit on the number of pictures you can post.
I have a myspace account and got really into it last summer though, haven't done much with it recently. Check about once a day to see the new pointless surveys my friends do and to maybe do a blog. Thats about it.
Besides without myspace though how woud you waste time at work?...oh yeah, MR 🙄
