Originally, to be sure, abbreviations were intended to serve the convenience of the reader by shortening names so that cumbersome phrases would not have to be repeated in their entirety. The purported simplifications actually simplified. But many writers - especially technical writers - seem to have lost sight of this goal: they allow abbreviated terms to proliferate, and their prose quickly becomes a hybrid-English system of hieroglyphs requiring the reader to refer constantly to the original uses of terms to grasp the meaning.
