Admittedly, it is also the sort of acronym that, when you don't know it, is really annoying in a headline.
I would have myself made the mistakes of assuming the terms is ubiquitous and everyone already knows it. I have heard it used liberally at every job I've done in the last 15 years.
I would have termed it a "very very common acronym." Right up there with API.
But your post reminds me that not everyone's experiences are the same.
Anyone had working experience with either?
