>> I dream of rallying all those independent YT ch. into their own network. We could call it ScienceWorld.Community! <<

That would be awesome.

You might like thefreaksclub. There's some alternative community building there too.

>>Time after time YT keeps going down the drain. I don't know when people will seriously wake up and stop putting up with it.<<

>>There's already CuriousityStream. <<

I've see a few of those too.

>>Imagine a PeerTube based community with phpBB forums, a microblog with status updates & Groups & socialized Listography implementation & pinboard & user gallery, newsletter, and other handy features like a YOURLS URL shotener, a pastebin, kanban board to organize tasks, and who knows what else...
All funded by user subscriptions, donations, privacy respecting self-hosted ads, merch, ....<<

Nice.
