I have a posterous blog that uses a custom domain. One thing that I would like is for the automatic tweeting of my posts to use my domain for the short url.<p>So something like <a href="http://hacketal.com/i-want-a-coffee-mug-like-this-one" rel="nofollow">http://hacketal.com/i-want-a-coffee-mug-like-this-one</a> should be posted as <a href="http://hacketal.com/random" rel="nofollow">http://hacketal.com/random</a> instead of <a href="http://post.ly/random" rel="nofollow">http://post.ly/random</a>
