It's my understanding of the system that if your are a host of a certain forum, you really only can drive consensus decisions for that forum. That being said if Skinner didn't want people to provide input across all the groups/forums he likely would have set up forum hosting differently, where you were blind to the actions of other hosts. (Clearly I can't speak for him).
I know I personally don't mind the feedback and input others have, but your right it doesn't mean I'll agree with it or use that input when reaching consensus.
When I responded to the previous poster they were asking for transparency, my suggestion to join as a host of another forum/group would give them that transparency immediately. Does that make sense?
