You need to penetrate and network through the friends+ network. Public worlds will always be RNG based. You need to build a list of friends who are interesting. Here in /vrg/ we got a colorful cast of characters. And there are a lot of groups like this one as well. But the vast majority stay mainly in friends+ instances.

Get on a meetup and start adding people and finding friends that are like minded. Also go and befriend friends of friends of friends.
If this is anything like real life, every other person is merely 6 jumps away.
You sound interesting though. I got a few possible things that might interest you if you are willing to take and talk on a stage. A sharing of ideas.
