I'm discovering there are two kinds of people in the world -- those that get Twitter and those that don't. If you're in the first group, you've got to check out "Zombie Attack" -- the first twittered work of fiction. No, I'm serious. This is great stuff.The story is that two brothers named Matt and Greg are on the run from the small town where they grew up, driven to become fugitives by an invasion of zombies that's caused by some weird virus, maybe. That's all I'm going to tell you. You can read the rest. In a couple of minutes. It's not War and Peace, after all, it's Twitter, which is sort of the point.

The proclaimed authors of "Zombie Attack" are two guys not so coincidently named Matt and Greg -- Matthew McInerney, whose blog says he's a student at the Savannah College of Art and Design, and Greg Spessot, who styles himself Krekko on Twitter. (McInerney leaves a little more of a Webtrail -- check out matthasalotofideas, but even there, Greg shows up occasionally as an agent provocateur.)

And while we're on the subject of Twitter, you've got to take a look at a mashup of Twitter and Google Maps called Twittervision.com. It is fascinating. It is hypnotic. Twittervision (the work of Dave Troy, who twitters, naturally, as davetroy) is, on some level, either a heretofore unachievable God-like perspective on humanity, or more boring than watching paint dry. Or both at once.
