Twitter's good for simple pieces of news, witty quips, and putdowns. That's about it. You can't actually communicate complex, novel ideas in 280 characters, and you still can't in 2800. The only redeeming feature of Twitter that draws these commentators to it is that all journalists are addicted to it, so your one-liners might get you some fame. People have made careers out of that.
