Unfortunately, pretty regularly across all the forums I post on/browse since the marketing mavens have over the decades done an excellent job of thoroughly confusing/misleading the 'dumb-masses' (as talk show host Neil Boortz likes to refer to the typical consumer). Then there's all the technical docs where the author wants to use his own jargon as much as practical for whatever reason(s) to define otherwise long since well documented physical conditions/events.
