Back in the good old days, acronyms seemed less common.   Early on, like many, I learned the rather posh RSVP (it's French, you know) and ASAP.   But once I entered the computer industry, the learning curve became steep.

FYI, in my first job as a junior scientific programmer, I was soon challenged when asked to write something PDQ.   I was comfortable with PDP-8A assembly, but had not learned PDQ yet.

As the years went on, it seemed companies such as IBM, NASA, NEC, HP, DEC, and even SUN were promoting use of acronyms.   It was (and apparently still is) the "in" thing.   Acronyms are not only showing up in emails and presentations, but now they are used to describe management styles & techniques as well:   MBWA, JIT, and JDI and the ruder JFDI.

Now, AFAIK, there isn't a standards body or steering committee managing acronyms.   It's more of a DIY job.   So keeping up can be interesting.

FYA, you might ROTFL when you hear that recently, I was unsure how to respond to a colleague who responded "LOL" to an email.   I thought he meant "Lots Of Love", not "Laughed Out Loud".

IMHO, acronyms and their mobile phone cousin, SMS language, should not be celebrated as great achievements in human communications.

BITGOD, communications seemed more civilised.   Back In The Good Old Days, your host never enquired "NE14T?"
