I've always had the feeling that it is the right approach just not very well communicated.
Steemit.inc has the ressources to concentrate on the blockchain development itself and steemit.com is treated as a proof of concept and there are many incentives for developpers to create Interfaces and enhance the user experience.
It is the non written strategy and i thing it is the right one.
the steem blockchain is much more than a simple blogging platform, and empowering outsiders to develop interfaces and uses while working on the blockchain itself is a brilliant formula.
