Best way to "promote" is to NEVER promote.
Show qanon.pub and POTUS' twats to your family/friends and "play dumb".
Ask them questions and suggest that some small group (sarcasm; tens of millions) of "Anons" have been "interpreting" these things and let the other person(s) "help" you learn. This way, those that want to become curious can do so in a non-defensive way.
