I had no clue there was even a "first vote" for algorithm. Last I recall algo options were being discussed on reddit, and all of a sudden I see the sticky about final call here.

I feel there was a major lapse in letting it be clear what was going on, and I would like to again request hybrid PoW/PoS. This split vote says it all. The strongest push from PoS only seems to be major bagholders or devs, who are probably major bagholders.
