It’s lengthier to communicate with IM at work with IM-words like ‘afk’ and ‘brb’ not understood.

On the same day I chanced upon this site called the Jargon File. Interesting read, and surprising how many of then I already knew.

That said, I’m still a bit taken aback that I get regular responses like “what’s afk?” and “huh? brb?” when I use them. Maybe generation gap.
