No idea if they'll stick to their stated direction this time, but if they do, I think this answers your question:
Anything we haven’t included in here, and there are plenty, because opportunities are so bountiful in this space, is not a focus for us. We encourage you to contribute and seek opportunities by picking up anything we aren’t covering, particularly if it contributes to STEEM and cryptocurrency adoption.
Of course, you have to actually believe them. It would not be fun for an entrepreneur to believe those words and stake out a path, just to have steemit change course again and use that ninja-mined stake to stomp all over them later.
Everything starts with a vision / an overall goal. In my opinion it’s nothing you can leave out and let someone else pick it up for you. You can’t have multiple visions for Steem - that’d be absolutely inefficient.
All projects ever built on Steem should aim to strengthen STEEM as a token, but you need to clearly define that so that everybody can identify with and work towards it.
