While I agree there are a TON of videos on how to do certain things, some of the quality of the video is appalling. Now, maybe I have high standards (seriously) but it pains me to watch really shaky, vertical iPhone video for 10 minutes about something that can be explained in 1. I'm trying to streamline the teaching, make things clear to understand, easy to see, simple for beginners, simple for everyone.
Oh and if I have to watch another person on youtube sip their precious homebrew/craft beer for 5 minutes and just smack their lips while they do a tasting and tell me about how good it is (and say NOTHING that actually describes the beer itself) I just might go nuts.
I think right now I'm at the phase where I want to take videos that have been done and outdo them with better information, better production, and make things simpler. However, I like your idea of doing some experiments and documenting the results via video and I will constantly keep this in mind and look for whacky things to experiment with, in the least, for a good video.
