What is a feed?
A feed is the most convenient way to be notified when a site changes. Instead of checking RecentChanges? every day to find out what's new, the site will send you an alert when it changes, which you can read in your news aggregator. (To receive alerts via email, you want MailPosts.) If you want to find feeds on other websites, look for terms or icons like "XML", "RSS", "Atom", "Subscribe", "Syndicate", "Bloglines", "Updates", or "News". Feeds are still fairly new, so the terms aren't standardized yet.
Feeds in PmWiki build on the WikiTrails idea. The page that is browsed with
More technically, a feed is a document written in the XML language, and following a syndication format like RSS or Atom. It will list the last N changes (N being whatever number the feed's maker decided it should be), and will give headlines. If the feed's maker decided to, there might also be summaries of the new content, or even the full text of the changed page.

What's the difference between RSS v1 and RSS v2?
Glad you asked! Back when the whole idea of RSS was invented it stood for RDF Site Summary where RDF stands for Resource Description Framework. Basically RDF was a way to describe meta-information about content using XML. The only problem with RSS back then was that it had very little to do with RDF (RDF headers were output, but the rest of the document was different XML than what RDF defined). So, anyway, this idea of RSS evolved for a time and gave birth to RSS v1.
Sometime later Dave Winer decided to redo the RSS spec and gave the acronym a new meaning -- Really Simple Syndication. Thus was born RSS v2 which was quite different from RSS v1 but still trying to accomplish the same goals.
