There should be some kind of ranking algorithm for "the best people on our side for talking to people on the other side." This is often very different from the people that my side enjoys listening to, since that often includes a lot of puffery about how our side is obviously correct to anyone with half-a-brain.
Where? I just paged through and saw a bunch of mildly controversial news headlines (which did seen an intriguing collection of conversation starters, like hard income limits for Medicare), and then a pile of ad spam for "hot celebrity pics" and testosterone for sale.
a) The best people of your side, may not be the best people to talk to the other side. Think rhetorics and clarity, vs depth, knowledge and insight.
b) It can be gamed, especially online, by people being moles.
c) There is usually a lot of context, "axioms" that make something "obvious" to you, but are too many to easily say to the other side.
