The top online RSS readers can be just as good as offline RSS feed readers thanks to AJAX and the Web 2.0 explosion. These web-based RSS readers often use drag-and-drop functionality to make using them a breeze. They are also free, which makes it easier to try out different ones until you find the reader you like.
