Memeorandum-like tool I envision

I'd like to see a tool like Memeorandum for rss feeds. You could then build a page for each topic. For example, I have my Bloglines feeds in folders. With this Memeorandum-like tool I envision, you could make each folder a page, then view all the feeds in that folder on one page. It would make skimming rss content a lot easier.
