So, I have this Facebook account that I don't really use much, except when friends contact me through it. But it seems like a useful tool, and lots of people (including gilana, whose post inspired this one) seem to like it. I just don't seem to have found the particular foldy bit of the Swiss Army knife that is particularly compelling for me. I'm looking for it, though and now I'm asking for help.
If you use it, what do you use it for? What bits do you like about it?
