Everything on this website exists somewhere on a spectrum from "ever-changing living document" to "list that occasionally gets appended to" to "opinion piece that will be irrelevant in a week".
Most of its content lives on the former end of that spectrum; this is a place for the stuff that's closer to having been written only once. Don't expect a given page to stay constant over time, though.
I track shorter opinions of mine at my small thoughts page.
