I confess I've been sucked in to the world of Twitter. It's kind of addictive, watching what folks like John Gruber, the Iconfactory boys, Maury McCown, and even Darth Vader, are up to. I'd love to know if my friends have accounts, so I can add you as a friend to mine, and please feel free to add me as a friend to yours. Ping me via IM, drop me an e-mail, or leave a comment. One cool thing Twitter did last week was they created a Macworld account. By adding this account as a friend, you could follow the postings of those at Macworld Expo as Steve announced the latest and greatest tech from our favorite fruit company. There were so many messages coming in to Twitter through AOL Instant Messenger that Twitter exceeded its allowable AIM traffic, and that service was unavailable for about a day. (To clarify, you couldn't post to Twitter via AIM; Twitter and AIM were each unaffected.) You can post to Twitter via your Twitter page, by instant message (Jabber or AIM), or by text message from your mobile phone. (Text message charges from your mobile provider apply, but there's no charge from Twitter.) If you're a Mac user, you can also use Maury McCown's TwitterPost, or the just-released-today Twitterrific from those aforementioned boys at the Iconfactory. Both apps are freeware. So the question remains, what are you doing?
