    Free Speech Just Pay Shipping

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

    ...It can be used like a forum or chatroom to associate text with responses, or to associate election candidates names with their positions on the issues, or to associate your website URL with things. Many possible uses, and a global competition for what gets associated to what else. In this peer to peer network, pairs of short text are communicated based on highest "proof of work" (see Bitcoin's design doc) on each pair, so the pairs of text that the most time is spent toward associating will spread through the network.
