Jon Udell is posting on the RSS redirection issue:

It's been almost three years since I first wrote about the problem of RSS feed redirection. From time to time I'm reminded that it's still a problem, and today I noticed that two of the blogs I read were affected by it. I was subscribed to John Ludwig at www.theludwigs.com/index.rdf, and today's entry says "Feed moved -- pls check out www.theludwigs.com/index.xml." In fact he's got an index.xml and an atom.xml, and the latter seems to correspond to what's actually published on the blog, but either way the issue is that we've still yet to agree on a standard way for newsreaders to follow relocated feeds.

Well, there's a solution already - HTTP redirect. I know, I know - as Jon says, not everyone controls their own server, and not all hosting providers will provide that service. Still, it seems like the KISS solution would be to advocate for hosting providers to agree to N days (weeks, whatever) of standard redirect service followed by a 410. Solves the entire problem, most aggregators already handle redirects - and it doesn't require the invention of funky one-off, feed level answers.

What am I missing?
