I'm usually logged in to facebook. It's nice to keep up with what some people are doing when I don't have time to give them a text or a call to everyone. I can just pop on scroll down and see "Hey, maybe I ought to make time to call Hicks... looks like he's having a bad time today" and see how he's feeling. There's also the clear "how much someone is talking to you/hates you" thing depending on whether they've deleted your ass or re-added you or whatever which whilst it sounds stupid can sometimes shine hope's light where it needs to go.
