Lawyers, platform moderation, and SEO have wiped it out. What’s left is boring drivel whose only purpose is to sell you a product or a course or avoid a lawsuit. I realize some have moved to private groups and there are still sites if you look hard enough. But is that enough?
Federation feels like the right place to bring that culture back rather than let it die or has that ship sailed?
Be the change you wish to see. Personally I’m not holding back information, sadly there is only so much I know about.
