I disagree, and maybe my tastes are niche. I’m a very amateur gunsmith and look up how-to’s on weird shit I can’t figure out. Often the answer is in the comments.

“This guy has mostly got it, but do step B before A.”

Or:

“I had this issue and fixed it with $X.”

I’d guess a lot of technical/mechanical/niche stuff works like that? I don’t look at the comments on popular stuff.
