The feeds are for: http://wikiriver.org/.
Another example: Salon has a WikiLeaks topic page, in HTML -- but doesn't appear to have a feed for that topic.
I expected CBS News to have a topic feed, since their site is (presumably) managed by the CNET people and they certainly understand feeds, but I couldn't find a feed there either. CNET itself is very confusing. They have a topic page for WikiLeaks, but it points to a feed for Politics. I included it in my scan, at least to begin with since it seems to have mostly WikiLeaks stuff in it.
