You really want more succinct videos than what he already makes? Although they may seem long in a modern day where people have the attention span of a gnat -- his videos are fantastic and to the point. He literally ignores a lot more complexities and drama surrounding a lot of issues. Does he ramble sometimes? Maybe, but the talks so fast at times that the video is over before I've even gotten half way through with my own research. And this is from someone who has followed him since he posted videos on spinning on your own VoIP server and when he was still based in NYC.
"An account of human suffering" (assuming I remember the approximate title) is one of his earlier videos that sticks out in my mind and one I'll never forget. It was a tongue-in-cheek nod to the fact board diagnostics for hardware that has obviously been abused by the end user is a tedious and often thankless process.
I learned a LOT from watching his videos, and I don't even do board repair! Psychology, business, the human condition...
