Why would changing the revenue model change the problem of discoverability of these channels, unless the problem is that these channels don't get enough money to pay for advertisement or increase their production values?
Well, I was thinking more in terms of discoverability. Like if we treat Wikipedia for answers about facts, we should have a place like that for videos. If there was a video about science, and people are looking for that content. My main struggle with Youtube it's discovery page, and content creators having to do certain things to compete with mediocre content.
