I’ve been playing with, partaking in, and following the developments concerning the automatic discovery of RSS feeds, written about extensively on dive into mark Basically, you insert the following code (note: it has changed slightly, so if you did this a while ago, double check your code):

<link rel=”alternate” type=”application/rss+xml” title=”RSS” href=”url/to/rss/file”>

The code goes in the <head> section of your html. You may have noticed my (experimental list) to the right. Just tinkering you see, but I think there are some real possibilities with it. I’m working on making it auto generate the list using PHP from a list of URL’s by reading the sites link tag. It’s quite simple.

Someday, when the google api supports this, you will be able to have content from sites that google believes is similar to your’s embeded into your site with some simple javascript.
