Me too. I have used them for things like stretching a pulse to drive a 
front paneal LED (which is totally non-critical), but I really work to 
avoid them in critical sections.

I think if I came across him, I'd shove the business end of a tesla coil 
'where the sun don't shine' :-)

I am strongly of the belief that one-shots (monostables, monoflops, call 
them what you will) should not be taught in electronics courses. By the 
time you know enought to find out for yourself how to design them, you 
also know enough _not_ to design them :-)
