This is awesome. I hadn't realized how interdependent these three are.

I haven't done the math, but it seems like just one site with a multi-million person user base that hooks into Steem could increase the value significantly overnight. They buy enough Steem to get all of their current users Steem accounts in one go, and suddenly the number of Steem users has doubled or tripled. Then they send a notification to their users saying "We just gave you X amount of Steem, and oh, by the way, you can now log into Steemit, Dlive, Partiko, and all these other sites."
