I've been keeping a running list of fediverse events going on for a while:
https://hackers.pub/@wakest/2026/upcoming-fediverse-events

I started the list on @hackerspub (1st screenshot) and it works pretty great, except that Mastodon (4th screenshot) doesn't display `articles` so it shows up here as just the title with a link and a OG preview which is really not great

It's pinned on https://activitypub.space > Technical Discussions
(2nd screenshot https://activitypub.space/topic/1bbcca92-7cf2-4c09-9454-5b882360061f)

@_elena of course! lemme know if you see things that need to be added. I have been moving the already happened ones here https://hackers.pub/@wakest/2026/fediverse-ecosystem-events-archive so you can see I have been adding these all year lol
