Sorry to hear that, but you get my point, I hope.

Hard disagree. I think freedom should be individual not collective. That doesn't mean arguing with strangers or being fed content by algorithms. And it doesn't mean that community is impossible either. It just means being in control of your own posting.

Let me correct that. It should be individual *and* collective. Collectives should be autonomous with regard to larger collectives and individuals should be autonomous with regard to collectives.

A successor to SSB? Where did you hear that and where can I read more about it?

I agree that community is good, but that community should still have sovereign identity. I don't really understand how those two things are supposed to be in conflict.

Oh yeah, I remember now.
One extra P and it would be the soundtrack to the game VVVVVV.
