I have an accessibility issue with The Old Reader, I contacted them about it and they never fixed it. In list view, there are no links to articles at all, if you're using a screen reader like I am. That makes me have to use the reader in expanded view. While I love the use of headings, it's one of the features on my wishlist for my absolute most epic RSS reader ever, (and it was a design feature of Google Reader,) I don't want to navigate passed the heading with the title, and 15 additional headings, because people seem to think that using headings is good for SEO.
Also, limiting the amount of feeds is a big nono in my book!! IF they didn't do that, and charged $10 monthly, I'd pay.
