For thoughtful response to thoughtful inquiry contact my email. Don't send me private direct messages on the Fediverse. If you have a general question ask it in a public timeline. I block users who send me annoying private messages about things that should be asked in a public timeline.

I sometimes post links to items I find curious, interesting, or of research and study value. This does not necessarily mean that I agree with the linked matter. Don't assume.
