We have to consider that people like Justin don't have the time for reading posts and responding to things unless it is their true passion to engage with individuals. So the key really is to be surrounded by the right, small handful of people.
I can only hope that's the case, because we can't rely on him to understand the entire ecosystem in a year, let alone a week - In the same way we can't expect Trump to understand the US political system in intimate detail. He just needs the explanations at the precise time its necessary to make an action.
Fingers crossed he knows what he's doing in this regard
