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.
