Well put Chris. Helping each other is what keeps this music alive and carrying on. It frustrates me when some musicians don't want to teach or help others.
Funny that Chris would criticize that playing, the rest of us just go "wow".
But it is for that reason videoing yourself is such a help. You see things you didn't realize you were doing. And for those of us not able to play with other people much, it very closely duplicates the nervousness that comes with playing in front of other people.
