Suggestion: give some to the @steemstem user who supports the #STEM and #CTIM communities. I would look at some communities that have started to grow and consider giving some of that stake to them with a condition that they cannot power down the charitable given stake (so they can use the charitable stake to support people who post quality content).
I like the other idea of burning the stake, only because it does equally reward all users who've taken a risk so far. However, some community members have done a fantastic job of helping their communities.
UPDATE: wrong user!
I absolutely agree @steemstem should get a massive SP delegation. What you're talking about is basically a delegation. The delegatee can vote with the stake, but it is still owned by the delegator.
A condition like that is not enforceable if they donated the Steem Power directly.
@null should get it all, all but a portion for a group of developers that can be awarded through winning a contest, a contest for developing the best interface for Steemit.com, one that includes a way to bend reward pool rape into a dating game where no means no and at the same time turns abusive whales into eunuchs.
