This is pretty much the only thing I use FB for, and even here it's not that much. It lets me keep tabs on people I rarely communicate with, and gives me a way to easily communicate with them if I want to say "hi" after a year of no communication. For people I'm not that close with (not enough to exchange phone numbers), it lets me keep a list of these mere acquaintances.
