Paul1977: You can Google them, but that takes up a lot more of your time compared to the 2 seconds saved by the person who typed the acronym. I personally don't like any time saving method that results in the other party having to expend more time.
Things like LOL and WTF are pretty universally recognised, but ones I've come across here that I've had to Google are IANAL, FTFY, SWMBO, YMMV, IIRC, and many others.
It's not the end of the world, but it is annoying to have to Google the meaning of something written in an English language forum.
I remember running into something like "This is a completely stupid idea SMH" and all I could think was "Sydney Morning Herald". Turns out that it means "shaking my head"...
So glad I'm not the only one... :)
