Birdhouse is a new kind of Twitter client for iPhone. Instead of focusing on keeping track of the most friends or supporting the most third-party services, Birdhouse is designed specifically for the composition and refinement of tweets. The app's developers, Adam "LonelySandwich" Lisagor and Cameron Hunt (who you might know as cameron.io.), are two guys who put a lot of thought into their tweets, and the design of Birdhouse really encourages users to raise the bar on their own posts.

Birdhouse isn't meant to be your main Twitter app. In fact, it doesn't display your Twitter feed at all. It's a minimal, no-fuss writing environment that's ideally suited to its medium. It neatly supports multiple Twitter accounts, storing your drafts for each and letting you give them a star rating, so you can get a quick visual read on how far along each one is. It also lets you manually back up your drafts to your email account for later use. Birdhouse also keeps track of your history of published tweets. It may not be for everyone, but I hope the mere fact that a tool like this exists makes people aware that Twitter can be more than another place to post your favorite links from Google Reader.
