After upgrading to Movable Type 4 templates, I’m still sorting out some kinks that pop up every now and then.
The most recent kink was spotted by [Jimmy Liew](http://cynics.info/) who noticed that my Feedburner feed hadn’t been updated in a while. Thanks, Jimmy!
Turns out that the ampersands in some of my category names were to blame. As there was a parsing error, Feedburner refused to process my feed. At least, I think that’s what happened.
This problem didn’t occur with my previous Movable Type templates, as far as I know.
