Tutorials on Youtube. Seeing the guitar thread earlier made me think. Could you get really good at something by just watching Youtube and following the tutorials. For instance I need to put gates on some decking and it looks easy enough to do. Cooking as well. Some of the Youtube videos make it easy for people who need some help. Has anybody mastered anything or built anything good after watching Youtube? Learned the guitar or something? Do you reckon it's possible to even become the best in the world at something by just using Youtube and the internet for research?
