I think you’re overestimating how many of these promoters could figure out how to set up a server by themselves. Most of the ones who can will just stick with the proven technology (email).
I want the technology to work out, I just don’t see it happening anytime soon. Think of Linux and Firefox; both have been best in category products for years, but neither one has an appreciable market share.

I am not talking about setting up a server by themselves.
Managed hosting is a thing. People can get their own media presence without any technical expertise for less than $40/year. (https://communick.com/services/takahe) I am just talking about getting them being curious enough to find a service provider that can do it for them.
