RSS feed fixed
I don’t really have time to dig out all that Creative Commons RDF stuff again, so I’ve fixed the RSS 0.92 feed by reverting to the default Wordpress version. Lacking the CC metadata, but that’s the lesser of two evils (the greater being nobody being able to use the feed at all).
EDIT: I’ve also re-instated the “link rel=” feed code in the page header, so that browsers such as Firefox will be able to auto-detect feeds for their own built-in feed reader features.
