It great that you are helping out, but I think that one of the ways that he would help get a following is if also promoted his Steem account in his YouTube. I know it isn't something that you can directly affect but if a few of his subscribers come over then they would be also supporting.

Granted it would be small, but I guess that is how it begins... But I find the same thing happens for professional content creators (artists and musicians) here, it is a place that sadly values amateur critique and curation over knowledgeable curation. It can be a tough pill to swallow...
