It don't think it is possible with a format like Twitter - I can imagine something like Wikipedia, but with sources limited to scientific publications, where each person improves upon a shared document. Maybe Google wave is a better fit, allowing rich non-text items to enter it. On Twitter you will have each person fight for their side, and you will never see a convergent product. Of course this answer (and your question) presupposes that we are trying to achieve some form of shared consensus, whereas on Twitter, it is really two or more sides of a culture war fighting and wars are zero or negative sum games. If we are trying to find the truth I benefit even if every theory I had was wrong, because it still helped us get to the one that works, but in a war if I don't win I am sure to lose.
