    3d peer to peer chatroom where associated pairs of text gravitate

    A 3d chatroom where the things people write gravitate toward eachother based on total strength of associations between those short texts. Strength is a competition of who spends the most computing time trying to associate the texts, similar to Bitcoin's "proof of work" system. While there is unlimited space in the system overall, the space around any specific text is limited by 3d space, which drives competition for what people want that text to be associated with. It can be used like a...
