As mentioned earlier, I can usually see thru the posers.
I watch people like Ron Spomer, Paul Harrel, Eric Cortina, X-Ring, Ryan Cleckner, among others and aware these all have credibility outside of You Tube. So I take more of what they say to heart.
Folks like Garand Thumb, Who-Tee-Who, and some others are more entertainment than education.
Then you have some like Backfire and Hickok 45 who have earned thier reputation from just plain honesty. I don't agree with some of thier opinions and preferences, but I don't have any problem recommending them to others.
Guys like the one the OP linked hopefully fade away before they further embarrass themselves, or worse.
