Thanks for making those "what-if" charts. I am grateful for Dan's witness approval votes for me. I am also proud to see that just with community votes I am fairly high on the list! I haven't campaigned much for votes so I really do appreciate it every time I see a new approval.

In regards to the Steemit Inc. accounts having enough stake in Steem to control the witness list, and the precedent set after the authkey hacks in July, you're on the money. By being able to vote for witness approval with these high staked accounts, Steem is technically and ultimately under Steemit control but this is known to witnesses with any amount of votes.

There exists a mostly unwritten social contract that Steemit won't abuse this. So far they've only used their stake in an extreme circumstance to mitigate damage from an exploit. That's not to say they might not use their stake in the future to turn the witness block into a rubber-stamp congress of sorts, in some imagined scenario where there's a large amount of dissent as to where Steem heads. That's possible and it's something Steemit users and Steem witnesses should all be aware of, so that the unwritten social contract gets reinforced.
