YouTube, like all forums, brings a diverse group of people together in terms of interest, skill, local norms, and reasonableness. I started following Buckn' Billy Ray back when he had about 5K subscribers as he reminds me very much of my childhood next door neighbor who moved in in '64. At age 83 he recently moved from next door to my parents to an assisted living facility. Up until about a year and a half--two years ago he was still scrounging and cutting, and then hand splitting firewood, to heat his house... a house my grandfather built. I helped him out with wood and used my 461 to cut up wood a tree service left him that was beyond the capacities of his saw.
Neither of them are particularly smart, both are kind of loud and fun loving, and they have some very specialized skills. My neighbor worked in commercial cabinet shops for most of his career and I learned some simple but important skills from him when I was a pre-teen. For one, how to apply contact cement without making a mess. When I was in Junior HS my woodworking shop teacher made something to which Formica was applied. He was making a hell of a mess with the contact cement. I explained to him how to avoid the mess... He didn't seem interested in what a Jr. HS kid had to say and from that point on I didn't take his instruction as being "the best" or "right" way to do anything... just a way.
I've picked up a few tips from BBR but much of his Vancouver Island related local knowledge isn't of any value to me here in upstate NY. I seldom deal with trees over 20-24" DBH nor over about 90' tall and all of them are hardwoods... BBR does "big" trees regularly and deals with primarily softwoods. Sharpening... picked up a few things to watch for when hand filing. His saw mechanic videos show more of a seat of the pants than a scientific approach to the saws themselves. I view him more as an entertainer than a source of information pertinent to my needs.
I checked out Ironhorse after hearing of him through BBR. Ironhorse spent a career dealing with the same kinds of tree and woods conditions as I. I picked up a few useful felling tricks that I added to my own tool kit of felling knowledge that was supported by GOL training. The single most useful Ironhorse video for me was "How a chip is formed! East coast sharpening tips!" This as it gave me a better understanding of the underlying theory/process that I needed to get repeatedly good hand sharpening results. Prior to that I was probably hitting 80-90% "good jobs" with unexplainable "not so good" ones thrown in.
After extracting those gems I've seen the rest of the videos as entertainment that I can simply skip if it's not interesting in the first few minutes. Same as goes for other well known channels... After a while the presenters run out of new material and they repeat the same basic things over and over again. I had a conversation with Roy Underhill about this issue about 6-7 years when I gave him a lead for a possible show... I knew him from my time working at Colonial Williamsburg, VA. Overall he hosted the Woodwright's Shop on PBS for 35 years. When I spoke to him he wasn't sure the show was going to be renewed by PBS and State Farm but he did get a couple more years after that. If you watch the entire 35 years of shows you'll find a lot of repetition encircled by a slightly different spin. This past summer while I was on my 1,200 mile bicycle trip I met up with a YouTube influencer in the lawn care/snow plowing business. We chatted for a couple hours. I joked with him about stumbling on his channel back when he had a couple thousand followers after like 5 years of publishing. I told him that I wondered why anyone would watch someone mow the lawn and he responded "I'm still trying to figure that out!" He has grown the business and the channel incredibly since I started watching and he seems to have some very good advisors.
There are clearly folks on YouTube that aren't worth watching at all as they aren't technically savoy nor are they entertainers. BBR and Ironhorse do have some good information but like any manual art there are often a multitude of ways to do things. I taught a "graduate class" on how to hand cut dovetails one time. On one long joint I used the methodology of a half dozen different guys from Fine Woodworking and on the web. When I was done I put the joint together and it went together the first time with no messing around. Why did this work? Because as long as you kept a few key points in mind NONE of the rest of it mattered!
