I can be emailed at tim (at this domain). Public GnuPG key is in pubkeys.asc, with fingerprint 790B EC31 3013 A867 2589 3ECD F774 6944 3D14 751E.

I can also be reached on Mastodon, which I have been exploring here and there. I am still on Twitter for the time being as well, though am feeling rather disengaged. In particular, I have started automatically removing posts and direct messages from there, using the excellent Semiphemeral tool.
