I love seeing ideas like this presented, especially in the place where is likely to be put into practice. I think that even if Steemit goes the way of the dodo, many great ideas about the interaction of social media, cryptocurrencies and the real world, like this post, will carry on and be used with future platforms. This site really is so cutting edge, I don't believe it's in danger of being replaced though. I think it will end up like Bitcoin did as a crypto. It will end up being like a "gold standard" by which all other social media will be modeled.
