Social Networking

Do you or someone you know enjoy social networking. I don't get too into it, but my wife just loves it. She has a lot of friends who are also part of these different social network sites, so it's fun for her to keep in touch. I also have lots of friends on these sites, but just am not on the internet enough to keep in touch with them. It seems like something that girls enjoy more than guys...am I right?! Maybe it's just me, I don't know?!?
