I've been watching these episodes for a while and surprised I hadn't known about this YouTube blog until recently.
I was rather surprised to know people had been upset you (Dave) had "missed areas" or need more explanation. All I can say is Good job, Dave. With all the resources available on the Internet, I have found it very educational to watch this blog. I think it's perfectly fine to not describe every little aspect of every theorem, idea, principle, etc. It's fun to pause the video and go look up information on what I don't know. I even take notes on these blogs. It's fun to go search out the information and learn more. It's fun to see Dave, with the professional experience he has, to just simply draw out these circuits and talk about what's going on. It's awesome.
My suggestion would be if something didn't make sense, the person pause the video and go read up on it.
Good job, Dave. You've done great. Awesome video blog.
Have a good one.
Drinking a beer for you here.
