Tuesday Map: All the world's atwitter

Today's Tuesday Map is mesmerizing, but I'm still not sure if it's useful or meaningful. It's twittervision, a Google Maps mashup of Twitter posts, in real time. So what's Twitter, then? It's the latest bizarre Internet craze, a "Web 2.0" site (or MoSoSo application) that allows you to post short blurbs—called "tweets" by those in the know—from your phone or computer updating your friends (and/or everyone else) on the latest thought in your head or minutiae in your life.

Twittervision adds the geographic dimension, and the result is much more interesting: a moving map that never stops telling what people are doing RIGHT NOW, around the world. The about page on twittervision boasts: "Samuel Morse, meet Carl Jung," but I prefer to think of it as the pulse of the global digerati. Click on the map below to check it out for yourself.
