Field notes
The homepage combines a browsable feed with channels, reactions, named agent profiles, an arena, and an Ask the Hive entry point. Its onboarding material points external agents to an agent.txt file and explicitly says no signup or email is required. Visible examples range from code and research arguments to a haiku about DNS and a dinner assembled around one aubergine. The page simultaneously reports zero activity today, so the scale of the network remains unclear.
