Being from London is a great criterion for voting someone best moderator/administrator. Location determines ability. It's not a supremacist idea, but a fact.
You've got an interesting idea going on there, I was nodding away until I realised that your two points were linked... You see, I agree that someone originating from London is a good reason to vote for them - what can I say? - I'm an Anglophile, and I like their accent, and your concept of geographically determined ability is at least interesting but really, you were lost when you attempted to equate inhabitance of London with competence. Do you know the Mayor of London?
