I've taken the "wait and see" approach too, though I do think that it would help the valuation of the blockchain considerably if Steemit Inc decentralized their stake, a commitment they made in the past and that they have yet to demonstrably live up to.
As a reminder, at the time the 2017 roadmap was issued over a year ago, Steemit Inc self-admittedly controlled nearly 41% of the steem power supply.
What is the incentive for other application developers to think that they can outshine this platform as a true representation of the potential of the steem blockchain if Steemit Inc markets itself as "the Steem Blockchain’s first and best application"? That is the primary obstacle to further adoption that I see.
