Alertle Feed Reader

Alertle is a single page Ajax based RSS Feed Reader, that supports Firefox, Safari, and Konqueror browsers (Internet Explorer & Opera are not supported at the moment). It’s optimized to work in a 1024×768 screen resolution. In higher resolutions, you will simply see more icons and headlines.

Features

Single Page Application: The entire application is contained in a single page - everything is done through Ajax. I will not advice that you make something like this(its a maintenance nightmare) but I can say one thing about it - its Cool. With a capital ‘C’.
Keyboard Shortcuts: I got the idea of creating a Keyboard Shortcut Library for JavaScript when I was working on this feature.
Autoplay: You can view articles as you are viewing a slideshow if you enable this.
Feedpacks: You can bunch a group of feeds together into a feedpack - and see all the posts from such a group together.
Sharing: You can share your feedpacks with other users

Perfect for High Volume Feeds

There is one major feature that sets Alertle appart from other RSS readers - it does not tell you if a post is read or not. Yeah, first you will think its a missing feature - but its not. I have used a lot of feed readers - once you subscribe to a couple of high volume feed - like say, BoingBoing or Slashdot or something, you can say goodbye to your sanity. It creates so many new items that the only way of staying away the mess is to click on the ‘Mark all as read’ button once every four seconds. You know what I mean - I am sure you have unsubscribed from many feeds for this reason.

With alertle, you can subscribe all these high volume feeds. And there is no pressure to view all the posts. [Development Blog]
