Had an idea. What if there was a distributed Twitter-like "Protocol" where tweets were posted to the network and were distributed based on the user subscription list? Make it so there was no central control that allowed a user (like Trump) or an organization (like Twitter) to censor any of the messages? It would have a standard API so anyone could write an app or webpage to interact with the network. Make it run on blockchain so messages couldn't be deleted by anyone.
Anyone could run a "node" which would basically be a server that ties into the network and allows a user's app to register subscriptions and post the messages to the network.
