While I want that to happen, I don't know if we can, so many people use Reddit. And I don't know if they're willing to leave. I talked to a friend and he said Reddit was convenient and he didn't want to switch.
when you are familiar with the enviroment you could make an account for him with a few communities he may like and then let him log in on a specific website. That way he has an easy entry and some content but not the front up confusion
