Zuckerberg uses Tweetdeck to Twitter. And likes it.

Last week it was revealed that Facebook chief executive Mark Zuckerberg has been using Twitter, the microblogging service he’s been trying to buy – since last May. His @zuck account remains private and largely unused, but he now has a new public one: @finkd. After the story broke he now has over 8,000 followers.

However, more interestingly, he has been trying out Tweetdeck, the desktop Adobe Air app for Twitter developed by UK-based Iain Dodsworth. Tweetdeck was recently funded for $500,000 by New York based Betaworks.

So, I guess if Mark decided eventually to pass on Twitter, he may well be interested in a powerful desktop client instead…
