The lecture slides are in Comic Sans, ugh.

edited to add: Dug up an actual comment from SPJ on this, I hadn't realized he uses Comic Sans for all his talks:

I suppose type designers or whoever might be particularly sensitive to whatever transgressions it commits (I dunno), but almost everybody I've seen indulge in a bit of C.S.-bashing seems to otherwise not care very much about typography at all.
As far as I can figure, it's just because people love a bandwagon, especially one that's really easy to hop onto and entails few risks....
