Nice, thanks for editing the post. Sociolinguistics is fascinating; at least not every kind of mismatch/misunderstanding is loaded. And there's a paper for some linguist to write on the hybrid tone of friendly and authoritative that forum moderators find to use.

I've been a public forum moderator for two or three days at this point. I'll probably find a lot of hybrid tones to use before there's a reliably good one. Your patience in the meantime is appreciated.
