I bought a twitter! But it won't work with my AOL. 
Okay, I joke. I use twitter every day, all day sometimes. It's a great way to communicate. I've talked to other industry folks, worked out reviews (both for my stuff and of other peoples work), discussed the ins and outs of rules and just about everything else you can think of over twitter.
If you're not using it and you do any of those things, you should seriously consider it.
