I really cannot nominate anyone. The names that come to mind are busy with other projects. Most minnows like myself are power hungry so I doubt if they would use this power well. Chances are if chosen, I might abuse this power and upvote based on favoritism and not merit.
However, if you're going to choose I hope you consider minnows in third-world countries because they really need it. There very few influencers in our sphere and we currently hold 1% of the steemit wealth. I'm don't saying minnows in other spheres do not deserve this opportunity, but for me its easier for some of them because most seteemit influencers are from Europe and North America.
This is a tough task you've taken upon yourself. I will love to see how this pans out.
