From the post:
Just added RSS links to many of my categories. They’ve always existed, I just figured it would be nice to include them in the category description.
This is a very good idea. Our site, like Ms. Haywood’s, is built with WordPress and outputs feeds for categories and tags by default. While I did note this behavior on our feeds page, I have not made an effort to promote our category feeds. Because I need to write meta descriptions for categories and tags in any event, I will add feed information to some of the more frequently updated sections.
