Theo, I really can't agree with this statement of yours. " I consider youtube is for entertanment, not education, on the whole."
For instance, when I bought my first lock-mitre bit I spent time on youtube Looking at videos showing how to set up the bit and chose a method that to ME looked easier than all the others. This is but one of so many cases, another one that sticks out was when I couldn't figure out how to remove the rear wiper on my Mazda 6 wagon, I found out in minutes. Again, when Marlene and I are prescribed a new medication I look it up on the net, not just one post but several posts.
I normally do get answers and whilst searching usually have my choice of music playing on youtube. So, in conclusion I would agree with your statement if it read :
entertainment AND education.
