I don't really salute, as I don't really know most of you, and hence can't remark on your character. That by no means excludes some sort of compliment or positive remark after a good fight, or an odd situation, incredibly lucky shot, etc, but the only reason I ever saluted was that was the etiquette taught to me in AW, and over time, at least for me, it really lost all sincerity, and pretty much became just a form of greeting or a kneejerk response.
Given the number of I've received after being vulched, or killed in 10 to 1 odds, etc, I'd have to say that a lot of other folks aren't using it as a sincere showing of respect or in a complimentary fashion either.
