You've done a really good job here. A news reader that lets me both rate news, theoretically learns my preferences over time, and lets me read the entire article without clicking more than once, is a serious package. (Why can't other readers get those things right?) My only problem is I'd prefer a native reader app to a web-based one, just because the major upside of using a reader is that it's constantly fetching and storing my feeds so there's no wait when I want to go read some news. I may check out your iPhone app though.
