Actually I don’t think that’s a hint to SMTs. The blockchain behind, the DPOS setup is what makes SMTs possible in the first place.
Already now you can build apps on the blockchain and create great verticals as we’ve seen with for example Utopian. A while back I wrote that Steemit’s UX is poor by design and that’s a great thing.
The platform exists already, but so far it’s version 1.x. SMTs will be version 2.
