I really don't understand enough about coding, programming, and tech aspects behind the blockchain - though think things could REALLY take off when such integrations become possible and get executed...
I suppose it may eventually not be so different than something like Facebook, that allows developers to develop and integrate their own apps.
surely, if Synereo were to adapt and leverage the foundational base Steemit's already managed to establish, they could probably get up to speed pretty quickly, rather than keep dragging their asses on starting their own foundation.
and I suppose, there's no saying that someone couldn't develop the infrastructure to integrate other cryptocurrencies as well. that'd probably surely grow the strength of this ecosystem, without having to force users to exit onto another platform to exchange into/ out of other tokens...
