Could a support feature supplement the great answer feature?

I think Fluther would greatly benefit from a supporter meter, and by that I mean a way to see how the public leans in support of two peoples’ discourse, who has devolved a discussion into a defensive bout of retorts and bickering, and who is on point with facts. Maybe the people who support a particular side of a dialogue can cast their lot, and if enough people outweight somone on an issue, their text could be force whispered.

Naturally people would want to add their support to the side that they agree with, thus the popular opinions will win out, so perhaps moderators should get the choice to add the feature to a back and forth dialogue as long as it isnt an opinion based argument. In the fact based arguments this could help people pick out what is generally supported factually and has been checked and what hasn’t.

How does this feature sound to you? Would you use it, or would something similar be more helpful?
