It makes sense that when you mix a bunch of different people from different cultures or perhaps just different ways of doing things etc, into one group .. yeah. Things get tricky.. it is crazy to think everyone will agree on something like shared rewards. I think it is just tough, as it truly does affect everyone. So it's not just "oh some people are popular".. like elsewhere on the web.. as the reward is shared inflation.. not just some sort of outside advertisers. Makes it way different than anything we have seen I guess.
I think having communities will help this a bit.. as well as of course SMTs.. then it is not just everyone in one big bucket.
