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.
