As an RSS feed reader, two thoughts. First, I love the idea of the little images. You could even do full ad posts once a week and I wouldn't mind if it means supporting the site. Second, anyway to make the text "Featured Comments" a link to the post, just like the title is? It's a little thing, but on a long post, you'd have to scroll back up to the title to get to the page. Not a huge deal, but you may get more click throughs if it was a link.
