This blog is about recycled knowledge. That means there are often facts or ideas in it that I remember, but don't remember the source of. If you read this and recognize your own ideas, please let me know and I'll fix it up.
Sometimes I deliberately don't say where an idea comes from or mention people in a "background" sort of way, because I don't know if they want their names attached to something they wrote in a more private space than the Web five or ten years ago. If you are one of those, and you do want credit, again let me know.
