I just bought a house that has a light switch that controls nothing! How
do I trace what this switch is supposed to do without ripping out walls to
trace the wiring? Suggestions? (now... be nice) ;-)

I had one of these, too. At some point, I had a worker up in the attic who
mentioned that the attic fan wasn't running, though it was 90F+ out (and
thus, oh, 3,000F or so in the attic). I got an electrician out, who went
up, tromped around, then came down and quickly found the switch, said
"You're not gonna like this..." and turned the fan on. (Being a "sensible"
sort, I'd left the "useless" switch off...)

(Actually, he was there to do something else as well, so it didn't cost me
much; better than the time I spent $43 to learn how to reset a GFI
breaker -- it never occurred to me that the "half-tripped" position meant to
turn it OFF and then ON; I kept trying to turn it on, decided it was
physically busted, called the electrician...)
