Elon musk in two thousand ten sent around om wide email saying that there were weighed too many acronyms being used. He wrote, no one can actually remember all these acronyms, and people don't want to seem dumb in a meeting, so they just sit there in ignorance. If you start to use a lot of jargon and vernacular, as academics do, as people in government do, and so on, you can lose the meaning of the thing. There is a dark side to all this abbreviating, even if it's meant to theoretically con rstatus on someone by making them part of the inn group.
