Working in an environment where acronymns are a tradition, if not a religion, I've happily embraced their day to day use. It may well be violating all laws of pronunciation and letter placement, but just think of all those precious seconds I'm saving.
Shorthand in e-mail is a whole other deal. I'm still at a loss at to why people write u instead of you, w/ instead of with, mtg instead of meeting and the like. Can it really take that much longer to type properly? Maybe my inner monologue doesn't work like other people's, but I read w/ as 'wuh' and the sentence never ends up making sense.
Yes, I believe I am a hypocrite.
