This was a really cool read, the crawford method is a excellent way to get people involve on the creative process but there is a problem with the "like" system, actually it is the same problem that some political election have when there is more then one choices.
Most of the votes go to two or three major parties, not because they like it but because if they do not vote on the leaser evil party, the other major party is going to win. So even if they like or identify more with less voted parties, it is rare to vote on them.
I do not know how the like system was implemented but having more then one run with the major ideas is always good method to avoid that and people should never know who has the majority of votes at least till the end but that goes without saying.
Also the "after all 120 people are less likely to be wrong than one." does not always work, that is why there is mainstream media and a more underground media. More does not mean better, it depend of the group of people and how diverse and talented they are but that does not seem to be the problem with CDPR, still that statement is a slippery slope.
