Really nice! I really appreciate the focus on good design and clear presentation of data. Something seeming this "simple" is not actually simple! Well done. I spend most of my life considering online tools for consensus building, and this is one of the more innovative and well executed I have seen.
I would love to see modules for this kind of non-binary polling in our open source decision-making tool[0]. I have never been a fan of straight polling because it misses some critical aspects of the discussion by pre-supposing the options, and most issues are not best approached with a conflict-based method of "A vs B, one wins". In fact the real answer is often a synthesis or evolution beyond where anyone started. Many of our users have requested polls to do temperature checks or decide quickly between options, but I have resisted because I don't want to flatten discussions into only a limited set of options that might leave out important aspects. I much prefer your approach!
