Once upon a time, there was a desktop Twitter client called Tweetie. It was built by Loren Brichter of atebits, and I remember beta testing it round about the time I was hosting 140 The Twitter Conference in Mountain View.
As far as I can tell, though, after Twitter bought Tweetie and took over development on both iOS and the Mac OS, there’s been fairly little improvement on the app. Much of the new feature set built for the web (discover, etc) has never made it to desktop Twitter, and for some reason I still can’t email a tweet from the right click context menu.
Thanks in part to Twitter’s decision to impose a hard limit on activations for builders of Twitter clients, TweetBot’s desktop client is $20 – which is a bit steep for my taste. Not with a bang but a whimper.
Desktop Twitter clients, I miss you.
