content: I've tried correcting simple spelling and grammar mistakes. Things like "he was the the hedmaster". My corrections were deleted in minutes with no explanation.  As you've said, people stake-out certain articles as their territory, and refuse to let others change them in any way. Even a minor change requires a full on internet discussion, and like most normal people, it's simply not worth 2 hours of my time to correct the spelling of one word on a Wikipedia article I don't give a shit about.
