Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I'm new to the meta site, and this seems like a very simple question, but as I don't know the answer and google doesn't help i'm going to ask it anyway!

SO, SF and SU are mentioned in many questions and answers on the meta site, but what do these acronyms mean?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Note that sometimes, you'll even see SOFU. – Anthony Pegram Dec 2 '11 at 16:10
SO is Stack Overflow, SF is San Francisco, SU is Soviet Union – gnat Dec 2 '11 at 16:21
Note that you can use these as magic links in comments and chat: [so] is automagically transformed to Stack Overflow, [su] -> Super User, and [sf] -> Server Fault. – Kevin Vermeer Dec 2 '11 at 16:27

and as a bonus: MSO is this site, Meta Stack Overflow.

Where these the first of the stack Exchange sites? I'm just wondering why these sites are referenced with respect to reputation cross site privileges, yet the cooking site is not! It could of course just be what the authors of the questions thought important. – AidanO Dec 2 '11 at 16:07
@AidanO Yup, they're the first and the largest. They're referred to as the Stack Overflow Trilogy. – Jeremy Banks Dec 2 '11 at 16:08
@AidanO - Yep, the trilogy as they are called were the originals! – Moshe Dec 2 '11 at 16:09
Good to know. Thanks. – AidanO Dec 2 '11 at 16:10
@AidanO With respect to cross-site privileges: there shouldn't be anything different about these sites from the others. Either the post was written before the other sites were launched, or the author was just being selective. (Tiny exception: Stack Overflow and Meta Stack Overflow have separate rep systems, while the other metas just inherit reputation from their parent sites.) – Jeremy Banks Dec 2 '11 at 16:11
and SOFU is Stack|Server|Super Overflow Fault User – ChrisF Dec 2 '11 at 16:22
@Aidano - it probably is a bit of both "first" and "poster thinks they're more important" (note that I'm not saying the poster is right!). I know lots of "geeks who cook", and a few geeks that cycle and a few geeks who enjoy DIY and so on, on this group of sites but very few "cooks that geek", if that makes sense, and while that might just reflect that I'm antisocial and don't talk to enough people, I suspect that a lot of us came for one or more of the main sites and consider those the heart of the thing. – RobM Dec 2 '11 at 16:39
