A “site map” is a listing of your blog posts on your blog, like a table of contents. This is what the poorly named “Really Simple Sitemap” does. It should be “Really Simple Site Map”.

A “sitemap” is a hidden XML file that is read by Google, Yahoo, and other search engines as a guide to all your blog posts. It isn’t “readable” by humans since it is inside a bunch of code. That’s what the Google Sitemap Plugin does. That’s correctly named.

You might want to fix your post to correctly label what does what. You offer such great information, I’d hate to see this confusion be perpetuated.

Thanks and keep up the great work.
