I keep seeing new acronyms internet slang everyday on Stack Overflow.

Such as the following

* [YMMV](http://en.wiktionary.org/wiki/YMMV)
* [AFAIK](http://en.wiktionary.org/wiki/AFAIK#Initialism)
* [IMO](http://en.wiktionary.org/wiki/IMO#Initialism)
* [HTH](http://en.wiktionary.org/wiki/HTH)

Is it possible to make a stack rule guideline (or frequently asked questions entry) that, when you are answering a question, you **spell out** whatever acronym Internet slang you are using, because not all of us know what a lot of these mean?
