Thanks for stepping up!
Great list so far.
They've been mentioned below, but not on the list yet. @jesta and @lukestokes both have been around a long time and contributed a ton to Steem. They understand both the tech and the politics from a foundational perspective. Steem really needs their participation.
Glad to see Kevin there. Straight shooter, sharp, level head and outstanding integrity.
It'd be nice to see @donkeypong here too. He's one of the old timer quiet strengths of the community and has been invaluable to many projects, while managing to avoid the drama. How does he do that?
