Out of the lot, it really does seem that @surpassingoogle was the one who was making more on n impact on Steemit than the rest, I can't speak for all of them, but @surpassinggoogle, as you mentioned in your post itself did, in fact, seem to bring the most value in supporting and educating of minnows and aid the overall growth of Steemit and it's user base.

It'll be interesting to see where the @ned's SP will go after this.

My vote is for @curie to get come of that SP, the work they are doing is immense.

God Speed Brethren.
