5. What I would want as a candidate (a blunt and specific "warts and all" description of the team I'm joining) is not what employers would provide (vague, HR-y generalities like "we use cutting-edge technology" and "we prioritize work-life balance"). This was what turned me off from KeyValues.
But I hope these are tractable, because I very much like the OKCupid model and would use the product if these could be solved.
