Seriously, reeder is already a great experience for me. My app use looks very similar to your screenshots, but with the typography of reeder already baked in. With just a click I can: take notes, pinboard an article (or any link in the article or comments), parse whatever I'm looking at through instapaper, open any link in safari, tweet any of the links, share a story via google reader, email the link or text of an article. You should check it out, at the very least as a point of reference.
