I am wondering if there is any merit in having a convention for the use of acronyms and initialisms in our discussions? I have been working in electronics for the last 50 plus years but I have not been able to keep up totally with the frontiers or diversity of this science. I have to admit that many times, as I read a description or explanation written by one of the more up-to-date members, I do not understand what they are talking about. The problem is not the ordinary words associated with electronics but rather the PID, TTH, PMBD, ETC. While being able to communicate with such initialisms adds a sense of in-group it is certain to frighten off some of the aspiring beginners as well as the old guys (me). I would propose that when using the Initialism for the first time in a discussion we put it down written out one time first. For example: (We must communicate effectively) WMCE. If "not" WMCE then we are wasting our time. Anyone know if there is a dictionary of electronic initialisms?
