I realize that most of the regulars on this site (including me) are quite savvy in technical terms, in-universe lingo, and Internet-speak. But not everyone who looks for answers on this site may be.
Recently, I started seeing an abbreviation used on this site that I had not seen before; one that I could not deduce the meaning of. I had to look it up. It was TL;DR. It does seem like it's being used more and more in answers on this site, but in my opinion it seems sloppy to use memes like this. After all, users are flamed for using netchat or l33t speak when composing questions or answers instead of regular English. (IMHO) ;) The same thing could be accomplished by simply writing instead:
Short Answer: Yes, Virginia there is a Santa Claus
Long Answer: [...]
In that same vein, but maybe to a lesser degree, should we try to limit the use of universe abbreviations (e.g. ST:TWOK, ROTJ) unless first defined within the question or answer? It seems like it would improve search engine results, and minimize confusion of folks who don't know all the jargon.
