Pardon the very clickbaity title, this is about people that make youtube videos.
If you could set one of your favorite youtube peoples down a knowledge gathering path that would lead to videos being made, what would it be? I'd love to somehow see Mr (??? never seen a pronoun) Technology Connection pick up a sudden interest in 90s/00s car audio gear and make an extended Sights and Sounds series going through various head units and similar components. Doing kinda-but-not-quite ASMR videos showing their operation and features, and importantly all of the fancy lighting options.
Keep in mind the moment any old piece of technology gets youtube traffic, the scalpers and yuppies move in and you will never be able to reasonably afford your niche hobby again. :-(
Also in my case, one of the fun things about finding those videos is seeing whatever music happened to be playing, and I'd rather hear interesting things than youtube content library whatever stuff I'll never want to go hunt down on discogs and listen on it's own.
