Feedvalidator finds a couple of problems, but I'm not sure that they're related. http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fnews.ycombinator.com%2Frss http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fnews.ycombinator.com%2Frss Maybe try generating an Atom feed? Atom seems to be much better defined than any of the myriad competing RSS implementations. Or maybe toss a hyperlink into the description tag rather than the comments tag ... from what I see in the RSS 2.0 spec, comments is a more of a "should" rather than a "must". The spec itself refers to it as an optional element, and Winer (I think) says in a note that implementers "should" support it. Clearly some of them don't. :-)
