Google Reader, my feed reader of choice, has added drag and drop-ability to feeds. Google Reader featured a clunky way of organizing feeds, so being able to drag and drop is a really welcome addition. Google Reader also has a feed discovery page that will offer you suggestions of new sites based on what you’re reading now, along with data from your Web History. Don’t worry, Dan, it’s all automated.
What’s your Reader of choice? Google Reader seems to be king, though I have been digging the speed of the Bloglines Beta. I prefer web-based solutions so I can read anywhere.
