It's been great to see the new Google RSS Reader the last couple of weeks. It's the closest an online RSS reader has come to being great. I haven't yet tried the NewsGator online tool that I'll be entitled to as a Net News Wire customer but of the free newsreaders Google has a great one. However the competition has been good. As seen here Bloglines which has been around for a while and could have done hotkeys at any point in the past didn't do it until Google forced them to.
