The rules and opinions I express under the Usage, Formatting, and Style sections rely primarily on The Chicago Manual of Style, Garner’s Modern English Usage, The Elements of Style, and the New Oxford American Dictionary; I also note positions taken by the Publication Manual of the APA, the AP Stylebook, and Robert Binghurst’s The Elements of Typographic Style. I tend toward a prescriptive expression of written English, and all my opinions stand in good faith of clean and consistent writing.

I also, though less frequently, write about things other than English usage, which you can read under Essays. I will continue to add as I find more to quibble about.
