You know what I really like my RSS reader to do? Zoom in and out on command. Show me birds eye view (readable view) of everything, let me scroll fast, but then let me zoom in to the headlines which I may find interesting and then let me zoom in more for details without making me click to visit the site. By zoom-in and zoom-out I mean the way Prezi does it, i.e, the camera zoom in/out and not the Ctrl+ font increase of browser.
