I think it could be more useful/interesting (and much harder for vroom) if instead of a random anything and a potential random user node, you could have an advanced random. In other words like a random node with constraints. For example you could decide you want to see a random meditation or CUFP but don't want to go looking at user nodes, and SOPW questions....
