I posted this video on thegearpage(dot)net. It caused a lot of churn, chest beating, and claims that the chord substitution theory I teach is invalid. (See my article on Dodecaphonics). In the gearpage thread, one poster claimed over and over again that the chord substitutions were invalid and another poster hijacked the thread and kept attempting to change the whole point of my dominant 7 chord substitution method with his preference of using min7 chords over a Maj7 chord.
I don't mind a meaningful conversation but on guitar forums, there is so much chest beating and thread hijacking that it really gets discouraging.
