Whats most interesting is that this whole release is notable because hes treating his fans like humans.

Making content easily accessible, being very hesitant to be invasive with emailing, not pushy at all with marketing. Being honest about how much he made as well as the costs and process of creating it, etc.

This experiment is detached from all the bullshit about "social media marketing". It shows that effectively selling on the internet comes down to is a) be interesting b) have great content and c) be accessible in as many channels as possible as a human being not corporate PR speak.
