It's a persistent multiplayer cyberpunk world with avatars, text chat, proximity voice chat, shared spaces and a few weird places (like a moon where people go to scream after the AI agent destroys your code).
It is a sort of real time reddit where regions in the earth are science macroarea, and you can just explore alone the world, or keeping company at 2am while coding, or doing networking, or asking help to specialized people in real time.
N.b. The project is still evolving quickly. I intend to publish the client source later, but I don't want to freeze the architecture. I would like to have feedback.
