Sure, Twitter is the latest fad; however, its traffic has grown exponentially in the last two months. Perhaps in large part it's due to the fact that it's a no-spam/no ad medium. DonationCoder.com should have a presence on it by posting new topics as posts and gaining exposure to its smart programmers and its interesting posts by members. There are plenty of plugins for WordPress to auto-tweet blog posts; why not develop the same for DC?
















Only for Windows users, though. (Still one of the all-time great apps.)
