Missing Link

Will it some day be possible to properly feed my blogs through Twitter? http://mysite.net/xml/magazine.xml does not work through TwitterFeed, and using bit.ly posts shortened links that lead to a white page with my blog and some code dispersed throughout. The reason the former method wil not work is because the links back to my blog are all the same, anyone clicking the link to my SG network would be taken to the Magazine section itself, rather than the individual blog. TwitterFeed won't post any of the content because it reads each blog post the same, duplicates. I'm wondering if it has anything to do with my using my own domain.
