After nearly two years, I believe I finally have an Atom-formatted XML site feed working.
I don't really know what that even means, but somebody told me I should have it. And since I don't actually know what it is, I have no way to be absolutely sure it's working. I'm also told that Atom is vastly inferior to some other format at doing whatever it is they supposedly do. So I also now have a site feed in something called Feedburner, which is supposed to cover the other formats.
So, enjoy!....if you have any idea what the hell any of this is.
