I scraped the last few hundred pages of comments on Main and Discussion, and made a simple application for pulling the highest TF-IDF-scoring words for any given user.

I'll provide these values for the first ten respondents who want them. [Edit: that's ten]

EDIT: some meta-information - the corpus comprises 23.8 MB, and spans the past 400 comment pages on Main and Discussion (around six months and two and a half months respectively). The most prolific contributor is gwern with ~780kB. Eliezer clocks in at ~280kB.
