Recently mastodon.technology announced it was shutting down at the end of the year. It's been a great home for my postings and a bunch of people I follow. My mastodon.technology handle was even printed in my college newspaper (normally reporters' Twitter handles were used).
To fill the gap, Taavi and I have launched wikis.world, a Mastodon server for wiki enthusiasts. Please reach out to one of us for an invite!
