As far as I can tell, there are no good crypto communities. To be good, a community has to operate, work = solve problems with little to no issue.  Such is not possible with people who do not completely depend on their CREATOR.

But you may be lucky to find a community/forum ranked above normal World's standards. It would need to have very principled people who try as much as possible to operate or build things according to Bitcoin ideals.

Imagine a transparent forum where anyone is free to join with little-no permission, has fair rules, members can be anonymous,  can have unlimited account derived from the main account, no one is trusted.. as trustworthiness/authenticity of everything is proven before it's accepted, the state of any public post before it's changed is immutable, merit & reputation based grading allowing all contributions/deeds to go through compulsory grading, the best members lead via merit based ranking, has a deflationary currency, has marketplace for interdependent economic system, has different offices/departments for people or groups of people with special talents/skills, the forum leaders bring this talented people together to build great/good things, job is always available, workers are paid according to how well they do their works, etc

I think such a community or forum could operate as a parallel society based both on cyberspace and physical world.
