Moderation essentially serves 2 functions.
One of them, the one Amazeroth is better at, is resolution of problems and conflicts, and so on. This requires someone who is fair, and who is trusted to be unbiased.
The second function is dealing with daily repetitive/technical tasks like addressing inactive parties and multiple accounts, deleting old bills and treaties, triggering early elections, passing on bug reports to Wouter after confirming that something is unusual, etc. | This requires someone who is active.
We may not be able to find someone who is perfect at both. We may very well need 2 mods, with one focusing more on the first function.
