People always complain about my RSS because it usually works terribly. To be honest, it worked so poorly that all of my attempts to subscribe to my own feed to troubleshoot it have been failures.
Finally I decided that I was going to sit down and figure out what the problem was. After a bunch of dead ends, I FINALLY bit the bullet and disabled all of my plugins and then added them one by one to see if one of them broke it.
It was the plugin that made the chronological archive that used to be in the top right (now it just brings you to a blank page). Good riddance!
