Some of those people seem to be speaking so slow that it is excruciating to listen to them. When I find someone who speaks at a normal speed and I have to slow the video down, they usually have more interesting things to say.
That said, tinkering before and after youtube has been two different worlds. I really like having video to learn hands-on activities. I just wrapped up some mods to a Rancilio Silvia, and I noticed my workflow was videos, how-to guides and blog posts, broader electrical information documentation, part specific manuals / schematics, and my own past knowledge. I felt very efficient having been through the process before, and knowing when to lean on which resource. But the videos are by far the best resource to orient myself when first jumping in to the project, and thus save me a lot of time.
