Developer Loren Brichter said on the company’s blog:
First, despite the fact that it says 2.0 on the box, Tweetie 2 is a 1.0 at heart (it really is a complete rewrite). From what I’ve gathered, it seems to be mostly solid, but like any 1.0 app, there are always those niggles that crop up at the last minute and make you want to kick yourself. They’ll be fixed soon.
Second, there are a ton of cool new features getting turned on soon on Twitter’s end. I built Tweetie 2 to take advantage of them, so I’m hoping to “flip the switch” for the next update. New style Retweets, per-tweet geotagging and, of course, Lists.
Finally, once things settle down a bit, I’d like to share some of the stuff I wrote that helped get Tweetie 2 off the ground. Code, ideas, and a few new projects.
