I'm pretty addicted to it, I ain't gonna lie. I do use it to keep in touch with old friends. I'm guilty of over sharing though. I try to post things that are inspiring or at the very least funny. 90% of my news feed is pictures other people post. It is kind of pointless, but when you're a stay at home mom it helps to talk to adults during the day!
I've kept in touch with folks through facebook I normally wouldn't have-It's fast, it's easy. I believe it's no different than any other means of communication. Is a hand written letter taking weeks to get somewhere somehow better? is my message to my friends and family any less personal because I didn't handwrite it? Plus you can creep. It just doesn't get any better. ha ha
I guess creeping on people is pretty nice sometimes I find it more interesting on here. Most of the stuff I read is relevant or important.
I have a Facebook.. and I hate it, but I kind of need it if I want to stay in practical contact with people. Such a pain in the arse haha.
