I am trying to do the same, I have been reading a bit about it lately, here is some of the stuff I have come accross that might be helpful (this s actually from MyYahoo):
How do I find RSS sources for my page?
Any site that supports RSS can be added to My Yahoo!. You can start by browsing through one of the directory categories on the Add Content page. Or try typing a keyword into the �Find Content� box.
You are also welcome to start with the Yahoo! Directory or search for RSS. You'll quickly discover there are several RSS directories on the Web today that are very helpful. Here are some of the better-known resources for finding RSS feeds:
* BloogZ:
http://www.bloogz.com/rssfinder
* Syndic8:
http://www.syndic8.com
* Technorati:
http://www.technorati.com
* Daypop:
http://www.daypop.com
How do I learn more about RSS?
There's lots of information on the Web about RSS. Depending on what you're looking for, try starting here:

And here are some other sites that offer feeds... I have not actually got any set, I am still not 100% sure of how to do that, plus my site isn't quite ready for it yet, anyway...
