Attensa’s online feed aggregator.

For the past couple days I have been playing around with Attensa’s online version of their feed aggregator. It’s built entirely on AJAX which makes it really fast. There is a lack of support/help on the actual feed reader page which is a bit annoying (the buttons aren’t labeled, it’s just trial and error right now, and no links to help or contact page).
You can view your feeds in three different ways, which I find very cool. The first way is much like you would read e-mails, with just the titles displayed and then clicking on them opens the post up in another pane. Or, you can do the same thing but with excerpts, then click to view the whole post. Lastly, you can chose to have Attensa display the whole post and no clicking is needed.
You also have the River of News option, or just clicking on a subscription to view the new posts.
All in all, very well done. I haven’t quite seen enough to switch from Bloglines, but I’m getting there.
