The crypto-economization of the social spheres, in my view is in it's earliest phaze of adoption/integration. Communities come in many flavors . Did that chinese steemit-like site (yoyow) ever launch?
Steemit was inspired by reddit, but instead of cultivating a non-monetary reputation based ecosystem (karma), Dan and Ned decided to go for the money. Which makes $ense. I like to think of 'crypto-economization' as a feature that can be interwoven throughout a community. The same is true with socialization itself. The opportunity to socialize is just another feature that has been encoded and made available for a cluster of nodes to engage with. There will be many 'steemit-like' portals (crypto-economized ecosystems.) Just like there are now many sixdegrees-like social spheres.
That said, steemit is going to be a massive success. Especially the more decentralized and distributed it becomes.
