TLDR: The r/selfhosted subreddit has a Discord server. The owner’s account got hacked leaving the server in a precarious state. They submitted a support ticket, but Discord has not taken action in weeks and probably won’t at all, so they are considering starting a new Discord server.
I don’t get what you mean by organic process. But sure, if you don’t think many people getting into self hosting would look something up like that, I get that you don’t think it’s worthwhile for a self hosting community being present on those platforms.
I mean it like, it’s a slow progression that builds on other interests, rather than your average person deciding suddenly to self-host. And it’s not that I think it is or isn’t worthwhile, I just have a different idea about what “we” are trying to accomplish. If your priority is to grow the userbase of one particular community or project, then I can see why you would want to have “presence” on corporate platforms. I still think it warrants an examination of the principles of self-hosting and consideration of “alternative” platforms.
