Recently, Pageflakes released their new RSS Reader. It provides all the features of a good desktop RSS reader and with AJAX, it gives you the smoothness of regular desktop reader. The good thing of a web application is that you don't have to install it in your PC and you can use it from anywhere.
The reader has two view modes: Outlook View & Newspaper View. In both view mode, you can resize the panes just like any desktop application. You can also use hotkeys for navigation. At the bottom, there are a number of options for sorting, marking the articles read/unread etc.
The reader also has option to save articles. You can save unlimited number of articles (in beta version). Even after few months or even years, you can still keep you feeds. Pageflakes also archives old feeds for a period of time. So, if you are busy for a day and couldn't read your favorite articles, it will be saved there for you. The Forward article option allows you to share your articles with others.
This RSS Reader is actually a part of the RSS flake. You can import your OPML or add feeds directly into the page or save as bookmark. The pre-caching feature is coming soon. With that, you can configure the reader to download feeds in background and read articles even smoother.
