I mean back when youtube loaded quickly and wasn’t chock full of spammy ads and self promotion, this was a lot more convenient for a lot of things than trying to find a text tutorial (with good pictures if you were lucky). Some things id definitely rather have the instructions there on the page where i can refer back and check them, but for a lot of quick tasks it was way simpler to just search on youtube and watch a 30 second video of someone doing it. These days that 30 second video would be 10+ minutes with multiple ads and sponsor call outs though.
