This video on the history of weights and measures is one of the gems of youTube. It has 2.3 million views (but should have more) what changes would send youTube in the direction of incentivizing this kind of content?
This video is clearly a passion project. The guy who made it was going to make it regardless. As a project the topic and the time required to research, script, film and edit is prohibitive. I feel like people don't get that.
