Mad Social Scientist

While reading Caroline Alexander's "The Bounty" yesterday, I noticed she used the punctuation "!?" as if it were a legitimate mark. I've always found this formulation clumsy and unprofessional, and pondered what we should use instead to indicate bafflement. I came up with this symbol on the spur of the moment, only to randomly discover it today (while reading an unrelated article on AT&T's advertizing). My idea was forseen by a mere 42 years. Oh well.

Now to see if it can be found in Latex...
