I can count on one hand the number of people I know that fit (what I think is) the criteria for the Fediverse:
A. Possesses the technical ability to set up their own instance or configure the clients
B. Understands the value of decentralized platforms and holds those values themselves
C. Knows more than 1-2 people who ALSO meet the qualifications of A and B (aside from me)
I think this leaves two possibilities: 1. There can be a small number of large instances, which removes the issues caused by A and B but has the effect of reducing most of the benefits found in B (focus, privacy, catered speech, etc).
2. There will need to be a million tiny silo'd instances (<5 people). This solves B, but we run into the issues of A and C. I realize this is closer to the goal.
I'd love to see Fediverse “platforms” succeed, but I'm not sure how they can since the network effect is what is needed.
