Gotta say, I just don't get twitter. But, for those of you that do, should AoPS use it for anything? If so, how should we use it? (Note to those of you who have asked to "follow" me on Twitter: I haven't approved anyone yet because I was originally using it to tell me when there were AoPS server problems. If I come up with anything interesting to do with it, I'll accept all the followers...)
