RSS2 comments
Dave Winer: When Radio reads an RSS feed that contains
links to comments, it shows them on the News page, so if you read
something there and want to comment (and the site supports them)
you can just click on the Comments link and you're
there. I'm in. I've added a comments element to my
rss2
feed. I also continue to provide the number of
comments made on the entry to date.
