Apparently some people were using http://jasonpenney.net/blog/feed as my feed URL instead of http://jasonpenney.net/feed. I’m not sure where the first URL came from, or why it worked, or why it stopped working, but they now both go to the same place. So if I seem to have disappeared for a while, that’s probably what caused it. You may want to change to the correct feed link just to be sure it doesn’t happen again.
