I modified the RSS feed template for this site. Entries are now piped through the TWiki, and the output is massaged to be RSS Valid. The only gotcha so far is I can't use the "nop" tag, as it results in a relative link that breaks validation. The end result is an RSS feed with working links to my picture gallery and Wiki site. Not that I've ever used RSS, but looking at the access logs, somebody is grabbing it. I've also applied a creative commons license to my content. The details.
