IMO its not a case if acronyms are existing or not.
It's rather a case of using them in the right context.
If youre talking to a newbie who isnt familiar with the Meat Loaf world, then using acronyms like IACBTMN, CHSIB or WTTN might be a bit out of tune.
But amongst a group of 'insiders' what speaks against it?
And lets not make the situation more difficult than it is. 99% of the acronyms are understood by the vast majority, and if its easier to write BOOH then Bat out of Hell, wny dont do it?
It's only i guess about 5% of the times that un-understandable acronyms are posted. And even if so, a little bit of thinking doesnt hurt anyone

and worst case theres stlll a list with most of the ML world acronyms flying around somewhere....
