I continue to be surprised (I believe I commented on this last year) that under "Academic fields" pure mathematics is not listed on its own; it is also not clear to me that pure mathematics is a hard science; relatedly, are non-computer science engineering folk expected to write in answers?

I second this: please include pure mathematics. I imagine there are a fair few of us, and there's no agreed upon way to categorize it. I remember being annoyed about this last year. (I'm pretty sure I marked "hard sciences".)
