The 140-character limit on each post is one of the most appealing things about Twitter, but it can also be one of the most annoying. That's why uri.is was created. You can write as much as you want and click to post to Twitter, and uri.is will link to your full text via a shortened URL instead of cutting you off. Sometimes you have something that's too long to tweet, but not long enough or permanent enough to post on your blog, so uri.is offers something in between.

Uri.is was built in a weekend, but it's already got some good features, like auto-shortening URLs within your posts, to make sure as much of your long post as possible actually goes out to Twitter. The developer reports that he's interested in having uri.is integrated with a major Twitter app like Seesmic or Tweetdeck, which is really the only way to achieve the goal of making it as easy to post long messages to Twitter as short ones. A bookmarklet or a Greasemonkey script would perhaps be more realistic ways to improve the service, so it's nice to see that those are in the works, too.
