One of the most obnoxious features of Thunderbird-as-RSS-reader is that when checking feeds it will display "http://feedurl.com/feed.xml is not a valid feed" in the status bar, but there doesn't seem to be any actual log of the broken ones anywhere, nor does there seem to be any way to view the errors as a list. I can export my list of feeds to an OPML file, but the only OPML validators i've been able to find online only tell me if the opml file itself is a valid format, not whether any of the linked-to xml files are either 404-ing or otherwise broken. This leads to me to my followup: 1) Is there any way for Thunderbird to give me a list of feeds it considers to be broken and unretrievable OR 2) is there an online service that can take an opml file and check the links for validity?

I once read a book about a couple of autograph hounds who ranked celebrities by their willingness to meet with fans and sign autographs. If this system were ported to the web and opened to the public, allowing anyone who's had contact with a celebrity to rank their experience, how could you validate that the encounter actually happened?

What's wrong with this XML file? Why won't it validate at that precise link? Thanks!
