This is quite a good idea. I'm working on a very similar idea myself, except I use the feed's main page and link the feed stories to where they are on the main page. My criticism is largely the same, but I want to echo it so it becomes that much louder. First, an instant demo is invaluable. It teaches the user immediately what they are getting into without the login/signup cost. Also, you should let the user in right on signup (logging them in so they don't have to login in immediately after they confirm). If they don't confirm in 24 hours, gently remind them, and then in a month of no use, delete the account. Also, I wish organization of the feeds was easier so I could read the feeds that start with the letter 'Y' much quicker than having to load 50-some feeds first. This could go far, so hats off to you. I know from experience that this isn't easy.
