@djlink yeah the problem is that video bandwidth and maintenance is very very expensive, tons more expensive than text will ever be.
Alternatives to YouTube are really hard to create without costs skyrocketing, so I don't envision an alternative without some form of payment.
I think the nebula platform saw the writing on the wall a long time ago, but doubt they will ever be able to escalate to be like YouTube.
I can see individuals maintaining their own servers with videos of their own though.
