Jude from Golden here. Yes we will work very hard to keep to scientific consensus and reach that level of quality or higher. Please bear in mind this is not only crowdsourcing but there is automation in the collection of the information, that too will have its fair share of issues as well no doubt :> There is likely opportunity to auto detect cranky/racist/gaming behavior and we have some plans in that area. Feel free to shoot over ideas as well if you have further thoughts.
