A guestbook and welcome message for my atproto PDS - dame.is

Open Social (aka u don't need a bluesky to be part of the atmosphere):

AT friends #2: @snarfed.org of Bridgy Fed (@ap.brid.gy) - Jake Simonds's Blog
informal chats with people building excellent stuff on (or in this case around) ATProto

^ Bridges are cool. People can follow my bluesky from mastodon, and I can follow bridged mastodons on bluesky.

How Wafrn's Bluesky Integration works
I have seen some people that it is bridged, even me said it, but no, it is not a bridge.

^ Wafrn is maybe the greatest place in cyberspace. Seriously. Every time I go there something makes me laugh out loud.

I've mostly focused on 2025+ stuff because as a heuristic I'm often trying to read the latest whatever, but been impressed to find evidence that not just the CEO but a lot of people behind the scenes have been thinking hard about this space for a while.
