Dave Winer has started a site for RSS users.
"Everything a non-tech user needs to know about RSS 2.0"
in slightly related news, the new version of Opera has a sweet built-in feed reader. I'm going to play with it a little more and will hopefully be able to recommend it for my "user" friends if for no other reason than the fact that they can simply click the little orange XML button and read the feeds on sites. A feed reader in the browser just seems "right".
