It was hinted a few weeks back, but now Tapbots has released a public alpha of the Tweetbot Mac client. Alpha applications are always buggy, so Tapbots stresses that this shouldn’t be your go-to Twitter client just yet. However, if you’re into tinkering and testing things out, go ahead and download it now. I’m using it alongside Tweetdeck for now and it seems to be working just fine. Looks like Twitter’s Mac client, but with more pizazz!
