An interesting thing I have noticed with the RSS reader is that it both follows HTTP 3xx redirect responses (rock!) AND saves the newly received HTTP URL for the feed (not so rock...). The latter behavior will silently destroy a whole folder of RSS feeds if-- a) you're using free wifi in a cafe, and b) said wifi requires you to login through an HTTP proxy, and c) the dumb user (that's me!) doesn't login prior to refreshing the feeds. I couldn't figure out why none of my feeds would reload, investigated, and found they all point to http://wifi-texas.com/login/78705SH/ after I got some coffee. As a suggestion, I think this update-URL-on-3xx behavior could be improved by having the RSS reader save the new URL if and only if the new URL contains valid feed content.
