Seriously? You want to be able to join a community you might not be familiar with and understand the lingo/jargon off the bat? Of course people will abbreviate things when the word/phrase is sufficiently long, commonly used, and the abbreviation mutually understood (brb, tldr, OOP, etc.). There is no elitism involved, if you don't understand something either Google it or ask. No reason to act snobbish because people cater the the most common denominator in a community rather than the lowest.

Not exactly, what I'm arguing against is writing something technical, intended to educate non-experts in the field (the experts don't need your report/paper/thing) and then not providing them with the information they need to background research the things you refer to in abbreviations or acronyms.

And I'm not saying this is _my_ solution, this was literally taught to me in engineering first year.
