Its too bad this breaks youtube-dl. I found a series of videos on youtube that revolutionized the way I do drywall and I can remember waiting forever for youtube-dl to grab the entire playlist.
The gentleman in the video is Laurier. I sent him a message on FB thanking him for the videos, he is extremely friendly. There is actually a neat story behind the videos. The current playlist is slightly different than the original set. A while back someone paid him to take the original series offline for six months (under the theory that they were too helpful). Laurier took him up on his offer and when he put them back online the playlist was slightly different but still remarkably helpful. I am an order of magnitude faster now when I rock a room. The biggest change for me was using the concrete trowel instead of the normal 4/6/12 inch mud knife. That being said I did pick up a number of tips from all of the videos. The only thing I cannot do is freehand cuts with a tape measure and a blade, I still use the T.
I would suggest watching the entire playlist once before your next project starts and then watch the relevant video before each step as a refresher. I used to dread any project that involved drywall. When I do "habitat for humantiy"-esque projects now I try my hardest to be on the rocking team.
EDIT:
If you are skeptical about watching all the videos my big ah-ha moment came when I understood "mud control." This is a nice example:
