Well, it’s been over a year since I closed my Facebook account, but I recently realized that I needed some information from some old private messages on there, so I had to reactivate it.
I’m still not really keen on using it as some kind of all-encompassing social hub, but I figured that I may as well leave it open for one thing: to add Facebook Chat to Adium. The ‘old-school’ IM services like AIM and Yahoo seem to be rapidly dying out, and this is probably the best supplement/replacement to them right now.
