I've noticed for some time that the RSS links for individual diarists are broken -- they just lead to a FeedBurner error page saying "This feed is making a 'clunking' sound. This publisher's content was recently unavailable so FeedBurner cannot present it at this time." After a month or so of periodically checking to see if the problem had been fixed, I finally read the fine print on FeedBurner's error message: "Detail: There was a problem retrieving the feed: Error getting URL: 404 - Parameter required".
I looked at the feed URL, and sure enough, the user name parameter wasn't labeled as such:
http://feeds.feedburner.com/dailykos/user?Armando
So I tried adding a label:
http://feeds.feedburner.com/dailykos/user?user=Armando
And bingo! A valid feed!
Could somebody please make this change to the template for the diaries page so that it generates valid URLs!
