Have you tried eating any of those before posting this?

The Fediverse is still relatively “new” (in the sense that it really started gaining traction a few years ago) and the type of people you mentioned are just the first to know about it.

If we get enough support and the big problem social networks crack we’ll probably get a more diverse crowd later on. I doubt the Fediverse will become mainstream but it’s definitely more known now and becoming more popular.
