well that's not excuse. you should be polite with the users so they won't run off. i don't think RB yells at it's users. eom
I'm polite when politeness is appropriate and impolite when that's appropriate. First and foremost, I'm myself; not some corporate-speak sugar-coated customer support person. A person with that kind of personality wouldn't last a week.
But if other sites have admins that wear the kid gloves you prefer, well, that's what's so cool about having choices, eh.
