I wouldn't be opposed to posting a dynamic list of feeds on the about page.
To answer your parenthetical question: not very well. Since articles are sorted based on the weight of their feed, and since I only show the first few articles for each topic, articles from feeds with lower weights may rarely appear. They will, however, contribute to the overall weight of the topic and force it into the top ten.
