It's Supposed to be Standard, Right?

When I first set up this blog, I turned on the option to automatically publish an Atom feed. Personally, I prefer RSS, but it was no big deal. Once I had my blog set up, I decided to use a little JavaScript code to link my home page. At first it worked beautifully, but one day I discovered something funky going on. Apparently the code had changed. Somehow. Turns out, when I saved my last post the last post was formatted differently from all the others. My code was looking for one element, but it was getting another.
