Has anyone implemented the HN ranking algorithm for twitter feeds? Basically, if the same tweet gets retweeted, then it should show up higher. On the other hand, brand new tweets have a pretty high score initially because they are new, so you should still be able to achieve a mix of a "live stream" and bubble good links to the top.
