First the queers and furries build a space where they can be themselves.
Then the infosec folks find that it fits well with their values.
Then the communists flock to the first real alternative to capitalist monopoly on shortform burst communication.
Then the artists come to find new walls to paint and nobody to tell them no.
The intellectuals, the chroniclers, the priests and the prophets, singly and in droves.
Slowly, it builds. It's neat to build an oral history from inception. #mastodon
