Tested the waters in 2016... returned in April 2022 with one or two other people. The avatar is an Earth Day photo from a few years ago on my campus. Header image is lifted from my Twitter cover photo.
I'm not as gone from Twitter as I'd like, not yet. And in spite of the Bluesky board's politics I'm active there too, @ harmonygritz.bsky.social. You'll find my longtime "rainbow" profile image there, for now.
