Breadtube if it didn't suck.
Post videos you genuinely enjoy and want to share, duh. Celebrate the diversity of interests shared by chapochatters by posting a deep dive into Venetian kelp farming, I dunno. Also media criticism, bite-sized versions of left-wing theory, all the stuff you expected. But I am curious about that kelp farming thing now that you mentioned it.
Low effort / spam videos might be removed, especially weeb content.
There is a cytube that you can paste videos into and watch with whoever happens to be around. It's open submission unless there's something important to commandeer it with at the time.
A weekly watch party happens every Saturday (Sunday down under), with video nominations Saturday-Monday, voting Monday-Thursday. See the pin for whatever stage it's currently in.
Too fast on an ATV. Swerved to doge a car, got clipped, then tossed down a 350ft cliff and landed on a previously crashed car. 
Neighborhood next door used to have a bunch of far too young kids on Chinese atvs when they were booming in popularity like a decade ago, kids were always riding around without helmets and unsupervised. It stopped when one child died after running into a telephone pole at full speed without any safety gear on. Still can't believe the negligence of all the parents letting their tiny kids ride those things without helmets or supervision, and I say that as a motorcycle rider.
Nowadays the same thing is happening with e-bikes. I've seen kids riding those things all over the place in the most dangerous way possible. Now the trend seems to be the new "off-road" e-bikes. I see groups of them doing wheelies on the streets regularly. No adult in sight. Only a matter of time.
