I know I added a JSON interface to my comic's website a while back so that there would be a decent way to fetch comic data programatically, and yet I'm sort of hoping nobody really needs it yet as I keep changing parts of the format whenever I realize better ways to present stuff. Oops.
On the plus side, I've got an idea of how to finally make an old feature in the Autofox code work for me. It's not wise to keep arbitrary HTML in the data files anyway...
