From the post:

If the community reacts positively (based on karma and comments) we'll support the potential contributors' effort to complete the paper

I don't think you should put very much weight on the reaction from LW, given that much more polished papers often get low karma. E.g. both my "Responses to Catastrophic AGI Risk: A Survey" and my and Stuart's "How We're Predicting AI — or Failing to" are currently at only 11 upvotes and rather few comments. If even finished papers get that little of a reaction, I would expect that even many drafts that genuinely deserved a great reception would get little to no response.
