Its difficult to work outside of the community with decisions that are supposed to be for the benefit of the community.
The reasons that groups started to use discussion forums was because the viewpoint of the community that a leadership serves is important, it just needs to be pruned, tended and in some cases matured to meet the quality that the group aims to attain.
Sometimes this can mean flat agreement or flat disagreement, but by allowing concise and conscientious discussion of the reasoning why you can sway the opinion at large in your favour or atleast away from negative rebukes. And there are rare occasions sometimes even when you flat disagree with your community and they’re not acting in their own best interest you have to let things slide on a little or perhaps take another approach.
Discussion allows deep incite into the needs, desires and required approach the community needs which only gives the leadership more control and more leverage with less textual bloodshedding.
