It’s possible to dizzy people by stringing together acronyms like paper dolls. They are faster to use than an actual team name or tool (most of the time). You may even feel like you have more cache around the office because you’re always using acronyms that not everyone in the room knows. And of course there’s the typing – the countless key strokes saved by quickly hammering out a few letters instead of a few words.
It’s also possible to avoid acronyms, especially in situations when you can’t be entirely confident everyone will understand them.
In the first scenario you save a little time, and feel like an insider. In the second, you can be more clear and inclusive in your communications.
