Tangential, but I see the same arguments being made as I discuss completely abandoning social media this week - "But where else can we go to find out about X/Y/Z?".
I dunno, but we can figure that out, we always have. Maybe, like you said, we should just start with not desperately holding something like that together. Maybe not everyone in the world needs to be in the same place at the same time, maybe a hodgepodge is okay. But people have the need to inform and be informed, so a solution will eventually crop up.
