Sure it's faster to type... but it's nearly impossible sometimes to guess what the program does without running it! It would be nice if at least you had some idea what the program was just by looking at the name... is that so much to ask?? Let people make their own short aliases if the default (long) names are too long for them (i.e., they use the command a lot).
