Obama's Twitter goes silentS@barackobama: Please update your Twitter. Since last Tuesday's historic election, Barack Obama's Twitter account hasn't sent any messages. Some Internet President-Elect! He didn't even use Twitter to announce his transition website, change.gov — and what is Twitter for, really, if not spamming your friends with your latest URL? There's no better sign that his 127,196 followers have been pumped and dumped — Twittered into contributing money and time, and then passed over for more presidential means of communication. Like, say, press conferences.
