Shame you are unwilling to step up and test what you are learning. Must be an armchair quarterback complaining about everything.Absolutely not interested in this. I know a lot of people like to make a hit in social media, not me. I am still debating whether I want to write a patent application on some of my ideas in hifi amplifiers. I just got a patent last year that I was one of the designer of a system. Getting a name in social is the last thing that interested me.
