This is the direction I've been moving, and my cotributions to this space are microscopic compared to yours. There's just too much energy tied up in other peoples spaces, the product of which can blink out of existence without any warning or recourse. Too much focus has been put on building spaces that look and feel like mega-social sites. Falling into those tropes prevents us from focusing on creating something new and uniquely ours.
You have the tools to house your own communities. If you have the energy to do it, it's best to build them on a foundation you can trust.
