I kinda wanted to let this die since it was just talking outloud, but I said I would address it so...
First, it was more about lack of information than misinformation.
I like Marc and have enjoyed a lot of his content over the years.
As I alluded to I know Friday Live is basically off the cuff and would have given him even more slack except he had 3 of the questions printed out before hand so he knew he was talking about BS blades. Plus, keep in mind his chosen profession is that of a woodworking educator not simply a content creator there for the subs/likes and subsequent endorsements.
In the end I suppose it has more to do with the fact the whole thing comes off as use more or less any blade and that frustrates me because mystery and lack of attention to bandsaw tooling is one reason people often develop the impression it is just an odd duck machine that you should have around for that once a year cut you can't make easily with anything else.
Some of the things that specifically bugged me:
1. No caveats with the Woodslicer. No mention of how fast it dulls or that it can't be used for any curve cutting really.
2. No caveats with the discussion of carbide blades. First thing is always to determine if a particular saw will tension one, given the price for the RK was $150 from the person that posed the question it could very well be a 14" cast saw.
3. He could have helped the person with the match re cost effectiveness since he had all the numbers and just needed to add a reasonable number of times a carbide blade will outlast a carbon blade (and should define what a "regular" blade is). At the time I heard it my quick math said after 4 years the carbide blade will save money AND give a better finish in the mean time.
4. When he discussed wider blades he said something like "some people say" and listed the possibility of greater stability. 30 seconds to explain the very real benefits of beam strength and 20 more to give the caveat of within a saws tension ability. He further mentions people suggesting higher friction with wider blades. Blade width doesn;t increase friction since the backer behind the teeth should not contact the wood but ride in the wake of the kerf (save curve cutting but then only the trailing edge should touch the wood). Increased friction is a result of increased teeth rake and tearing out more wood. Perpetuating a myth I hadn;t even heard.
Now for a little different tack. I think Marc is very good at what he does, better than most youtube woodworking educators, many of them or simply look what I did or what can you do with 2x4s and pallet wood (both have their place but don't hold my attention, except to watch them while the news is on with the video muted while I scan their shop in the background for ideas). He has some great free tutorials, one that comes to mind is the router based inlay "class". I took Ng's class a year or two before Marc's video came out and honestly you get 70% of William's class for free. Also his Guild classes are excellent and are great skill builders. So The Wood Whisperer good...
I hate when people use the word bandsaw expert in the same sentence with my name, I am just a guy that really likes bandsaws and have for 30 years and in the course of that time has owned 40 or so different saws and used gods know how many blades. There are some things I consider myself an expert at but those are things I spent many years in school and a career worth of time honing and none of it remotely has to do with bandsaws.
Finally, I don't mind the criticism at all, I was thinking (typing) out loud I don't expect people to agree with the thoughtful things that come out of my mouth much less the half baked off the cuff stuff. Oh and before anyone thinks that I think I could do better, I know I couldn't. The only way I could keep people engaged in a bandsaw blade discussion on camera would be to cut off a finger each minute or show a kitten playing with a hippo while I droned on.
Of all the laws Brandolini's may be the most universally true.
Deep thought for the day:
Your bandsaw weighs more when you leave the spring compressed instead of relieving the tension.
