As you will notice, I have supplied 4 feeds for the entries on this site, and a feed for the comments. Individual entry feeds are available, as well as feeds for the categories. If you are confused about which feed to choose allow me to point out a few things.

1. The Atom and RSS 2.0 and RDF feeds each have the title of the post (with the number of words in the post in the title), the link to the post's permanent location, the author of the post, the date of the post, and the full text of the post.
2. The RSS 2.0 and RDF feeds also include the category of the post.
3. The Atom feed does not have the category.
4. The RSS 0.92 only has the title (with word count) and an excerpt of the post.

The bottom line: RSS 2.0 and RDF are the most complete feed (useful for offline reading) and the RSS 0.92 feed is the smallest feed (useful for notification).

Enjoy!
