some of the trouble in reasoning about "strategy for ethereum" is in the tension between:

(1) "strategy is choosing what not to do", and 

(2) ethereum is a large decentralized ecosystem with surface area that reaches both broad across the world and deep into it

I work for Ethereum at the Ethereum Foundation.

How about ensuring a playing field where different strategies can be played out? Very raw thoughts here but unlike corporate strategy which seems highly linear and mostly about resource utilisation, the application of subtraction as a strategy actually opens up our playing field for many ways to do things
