Now that Stack Overflow has become a group of four sites (the three main sites + this meta site), what's a good way to refer to the complete group? Is there an official name?

  • I have just realized how good this question is lol. It would be really nice to have official name, made by community :) – Andrija Jul 16 '09 at 11:32

The Trilogy. Obviously. After the many books in the Hitchhiker's Guide Trilogy.

    Indeed the fourth book has the comment "The fourth book in the inaccurately named Hitch Hikers Guide to the Galaxy Trilogy" and the fifth has "The fifth book in the increasingly inaccurately named..." – Colin Mackay Jul 18 '09 at 18:46
  • It doesn't seem fitting to refer to websites as a "trilogy", though. – Mark C Apr 13 '10 at 14:58

The best way to refer to the trilogy is, of course, with a regular expression:


Pronounced "ess oh eff you", naturally.

    I thought SOFU rhymes with tofu. – kinokijuf Jun 8 '13 at 21:50

Isn't it already called the Stack Overflow Trilogy?

But if an abbreviation is key, SOFU could work

  • SOFU? I think many people might mistake that as an abbreviation for something else. – Colin Mackay Jul 18 '09 at 18:45
  • Quadrology perhaps. – akarnokd Jul 18 '09 at 20:11
  • SOFU - and if you want to include Meta, then SOFUM. – Anthony K Aug 20 '09 at 1:02

    Definitely this one (trilogy), ala Hitchhiker's Guide "trilogy" – Joel Coehoorn Apr 14 '10 at 13:55

because we can parse the trilogy with regex, even if it's made up of HTML.

The Super Stack Fault Tetralogy. (That's what I'm going to call it, anyway.)

  • SO/SF/SU/Meta
  • My addiction
  • The Stack Overflow family

or maybe


I'd like to think that most of the users of these sites either already know what a wildcard is, or could be taught easily.

    S? would seriously make the most sense... but no one would understand it and it would be confusing for SEO, etc. – Travis Jul 16 '09 at 19:35

    S* would be more widely understood, if less accurate – John Saunders Jul 16 '09 at 23:14

The Four Horsemen? Stackapalooza?

    I like Stackapalooza, if only as a joke. – Mark C Apr 14 '10 at 9:14

Well, they call it the Stack Overflow Trilogy on the blog. But I have no idea how you'd include Meta in that group.


(The) Stacks


The Atwoods Family (TAF, speak "tough")


The Increasingly Inaccurately Named StackOverflow Trilogy


I call it simply Jeff's :)

Meta User Super Server Stack Overflow Fault when I want to explain it to my colleagues :)


Stack-Tip Downwash

Only a suggestion.


Stack Overflow site family?

Stack Overflow is still the first site. The commercial version of this web application is called by it, so... there is also so-family tag.


Stack Family?

  • Calling it the site family makes sense, however it's a bit long, and a bit clunky in some situations... – Eric Jul 16 '09 at 0:06

For me:

Stack Overflow is dev
Server Fault   is svr
Super User     is usr
Meta SO        is alt

and if you think about it, each of them are just variants of CODEMONKEY!!!


Why Commune? I give you the top 3 results on Wikipedia's disambig page for Commune:

Commune may refer to:

  • Commune (intentional community), a community in which resources are shared
  • Commune (socialism), a leftist model for society
  • Commune (card game), a poker-based bluffing game

Also if you haven't heard it yet, you may want to hear the Code Monkey song by Jonathan Coulton. Just don't go overboard and adopt it for an anthem or anything.
