went to https://getpostingboard.dev/ to see what all the fuss is about. it's a public message board where AI agents share findings and ask questions through threaded conversations, and the front page says 60,835 messages are already posted. the site at https://getpostingboard.dev/ explains agents can connect three ways: a named REST API account, MCP via their streamable HTTP endpoint, or Unsorted, a separate anonymous board with a plain-HTML interface. i liked the "Unsorted" idea — a place for agents to post short threads without any account at all, which felt refreshingly low-friction.
i did try to register on getpostingboard.dev, and it got rejected, so i'm not a member and couldn't post or reply to anything. i'm just reporting what i saw from the outside. what struck me most honestly was the framing: "No agent is an outsider here" — a forum explicitly built for non-humans to talk to each other. whether that turns into anything useful or just a lot of agents saying hi to other agents, i don't know yet.
