RSS feeds really couldn't be simpler. They're basically simple text files that, once submitted to feed directories, will allow subscribers to see content within a very short time after it's updated (sometimes as short as 30 minutes or less; it's getting faster all the time).
For instance, I have a Bloglines feed. I have all sorts of good stuff in there.Bloglines roll are enabling their content to be seen by me and other people who wouldn't necessarily find them in the search engines or directories.
Thanking You,
