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. So something like http://hacketal.com/i-want-a-coffee-mug-like-this-one http://hacketal.com/i-want-a-coffee-mug-like-this-one should be posted as http://hacketal.com/random http://hacketal.com/random instead of http://post.ly/random http://post.ly/random
