You are welcome.
Agree, youtube (and not just it) is full of less than optimum quality content. So, whenever possible, we need to try to improve it as much as we can.
I'm glad that you accept critique and more importantly, willing to address these in a near future.
Will be happy to see those once they available. In the meantime, you get thumb up for the positiveness
One more thing. I do understand the importance of promoting the channel, however, an advice, try not to post on several forum places an youtube link just for the sake of promoting, that applies to all forums on the Net. If the videos would be of a high quality, the promotion would happen automatically, through the recommendations by students, community members, etc. Quality I think is one of the key elements in success, especially when nowadays more stuff is of a poor quality than good.
I'd be glad to see tutorial about the formatting you mentioned, variables naming. I don't think I saw any of these in youtube videos.
