I will say - the more people it takes to reach a consensus on a decision, the longer that decision will take.
Good point. What I had in mind was not a group discussion on each member. Instead, and maybe this runs counter to Hubski's ideals, is each applicant would require a certain amount of approval votes to gain entrance, lets say 10 votes. There would be no disapprovals, just those 10 votes would be needed. And maybe these votes should be hidden from the public at large?
I love the thinking behind the idea, but the actual execution of it would prove very difficult imo. Also, it creates a sort of "moderator" vibe that I'm not too keen on. However, the thought that someone should be able to string a subject, verb and an object together prior to admittance is appealing.
