When I first heard of it, I didn't get it. Then I got it and thought -- that's really cool. Then I ungot it. Twitter is a mullet. It's not just a fad, but a fad that will embarrass us later.
Listen, I'm all for technology. And new things really require a shift in our mindset. I love the "global realtime-ness" of Twitter, and I'm sure that core product will still be around in five years. What form it will be in is hard to say, but I can guarantee you it will not be as Twitter, which will have become a zeitgeist-icon-of-infamy for this age in the same way Pets.com and Boo are for the dot com bubble.
