I find facebook to be a great tool to keep in touch. I make friends everywhere I go (and I go a lot) and don't have the time to call, email or mail them all to keep in touch. Facebook allows me to see what is going on in their lives and them mine with a simple login. It is like a big, ongoing conversation with all my friends. Kind of like sitting at a bar with a group of friends. There are many conversations going on. I might not participate directly in all of them, but I "hear' them just like when I'm at a party/bar or whatever.
