Google Chrome rendering XML as text for RSS feed
This is a known bug in chrome that has yet to be fixed, chrome does not display xml rss feeds with any formatting whatsoever.
Update: There is now an RSS subscription / reader extension for Chrome.
I had this same problem and I used "application/xml" and it fixed it right up. Chrome doesn't like "application/rss+xml".
Bottom line, RSS support isnt used by "majority" of users, and as such they are only implementing it as an extension, for now. The extension is available here:RSS SubscriptionExtension
