Nobel Prize winner Robert Solow once warned of the hazards of oversimplification, saying that one could call it the occupational hazard of being an economist—except that it was actually the occupation.
In the same way, one could say that it's the occupation of the Web services developer to make a company's intellectual property available to a wider range of users in a broader variety of ways. Unfortunately, there's no clear boundary between that occupation and the corresponding hazard of doing it too well.
