Checkbox attributes would be nice for building a comparison chart. Important attributes (to me): * tracks read/unread status at individual item level * keyboard-driven navigation (sadly, as far as I can tell, only Google really gets it here) * unlimited or large limit on items per feed (some only allow 10 articles, which makes it impossible to read hacker news, for example) * standalone accounts (google or facebook login not required)
