The only suggestion I would have is to somehow allow friendlier URLs. I would really like feedflix.com/icey for example. It would be worth signing up just for that.
Hi icey - while that's definitely possible, here's a simpler way:
Right now the username you get (typically something like xy-12345) is actually your Netflix username. So all you need to do is to log in to your Netflix account and set your Netflix username to "icey" and FeedFlix will catch up on the next refresh and your page will be feedflix.com/icey from that point on.
Btw, RWW covered FeedFlix a couple days ago: http://www.readwriteweb.com/archives/feedflix.php
