I wasted a lot of time reading Mad magazine as a kid. I remember reading one issue that explained why Tom Jones was more successful than Engelbert Humperdinck. According to Mad, a few people would notice Jones leaving a concert, ask him for an autograph, and he could provide them and dash off before he was seriously mobbed. Humperdinck, on the other hand, would take so long to sign his name that he'd be mobbed and injured. Like I said, I wasted a lot of time. I wonder sometimes if there aren't similar forces at work in the software world where cool names and acronyms displace ideas where the names are not quite as melodious. For example, if I asked you to decode some DTMF (Dual Tone Multi Frequency – touch tones from a phone) it is a good bet you'd want to use a Fourier transform.
