There is no set number of people from a Wiki we require or cap. If a Wiki wants to have only 2 reps, while another wants to have 10, then whatever. It's about pooling ideas, not politics.
Our staff is really not political. We abhor bureaucracy, and politics. As Ax said, most decisions are unanimous: either something fails and fails hard, or something is a runaway success. Even when we voted on the issue of creating the Coordinator position, we had clear unity to create the job, and then between the three people who were nominated, I was the clear choice, even if not 100%. And since then, I've made my duty here to not only do what those who voted for me expected and wanted, but to reassure those who didn't vote for me that I won't let them down. It's not about politics, it's just about NIWA. If Zelda Wiki somehow managed to comprise 33% of all NIWA Staffers, then it wouldn't matter. NIWA doesn't govern its wikis. It doesn't enforce anything. ZW cares about NIWA, and all that means is that their caring would get heard a little louder. Even then, that's part of what we have the Coordinator for. In a clear event of contentious bickering, I could step in and take control of a situation.
I feel like it's assumed we're incompetent or something.
