Well, at least we tell people to vote the claims "impacts" not likability. We haven't yet researched how well this works, but anecdotal evidence suggests that it does have some impact.

The heart, is just a thanks to the original author and doesn't impact the sorting.

We are going to do something drastic to the default impact shown, because we agree that the average is not really an interesting measure. 1-2 months.

I hope we are not overselling ourselves. We are no panacea, what we do, is facilitate and capture the reasoning of all viewpoints. This won't automatically lead to consensus. But at the very least you can now truly understand where others are coming from and write your opposing claims to whatever they consider being their strongest points.
