Here is a more interesting question:
How would you reinvent Usenet?
What Usenet did well was that it was completely decentralised, had zero cost of engagement (despite 'hundreds, if not thousands of dollars'), and was everywhere.
What Usenet did badly was that there was a complete absence of identity management or access controls, which meant no accountability, which meant widespread abuse; and no intelligence about transmitting messages, which meant that every server had to have a copy of the entire distributed database, which meant it wouldn't scale.
It's a tough problem. You need some way to propagate good messages while penalising bad messages in an environment where you cannot algorithmically determine what good or bad is, or have a single unified view of all messages, all users, or even all servers. And how do you deal with bad actor servers? You know that somewhere, there's a Santor and Ciegel who are trying to game the system in order to spam everyone with the next Green Card Lottery...
