On the creator side, YouTube won’t monetize you until you have 1000 subs.
Which means the person that put up 1 video with a massive amount of views will get squat (but Google will gladly put in ads and take a 100% cut).
Protip: subscribe to creators that post useful but not very subscribeable videos. Sucks for creators that put up videos that don’t really relate to eachother.
Dunno why everything has to be a “channel”. That’s what search is supposed to be for.
