(sorry for accidental double post)
If I may respectfully offer my opinion on this whole issue...
Pebber, you're a good teacher, I liked your down to earth style and you're putting some good information out there that motivated, aspiring guitarists can apply to improve their playing.
My advice for what it's worth would be to disable youtube comments, and direct people to this forum in the video description. There are two types of people out there, people that wanna learn and people that already think they know how to do it and waste their time writing abuse on the internet.
The first group will take the time to ask intelligent questions and find the good information. The second group will move on to abuse someone else. The first group are the ones who are gonna put the effort in and get really good at guitar. It is a waste of time and energy to focus on those who barge in with abuse and counterproductive comments.
You're a great teacher bro. Direct your energies towards those that actually WANT the information, ignore the guys that wade in with abuse, and you'll help even more guys improve their guitar playing.
