What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 133 Stack Exchange communities.

Being the first and busiest site on the SE network, I suppose that there are some differences between Stack Overflow, and the rest of the sites. The one difference I'm aware of is the Interesting tab.

There are lots of customizations that only apply to a subset of the SE sites; it's not just "SO" and "everyone else" –  Michael Mrozek Jan 23 '11 at 20:15

Stack Overflow is running the same code as the rest* of the Stack Exchange sites.

There is, naturally, some degree of customization per-site.

On SO, you have:

  • the interesting tab (and no active tab, though you can still get at it for now)
    • meta.SO has [bugs] and [reqs] tabs, Stack Apps has the [apps] tab (I think that's it for custom tabs)
  • code syntax highlighting for basically all the languages supported by prettify
    • some SE sites have subsets of this (LaTeX on tex.se for instance)
  • User searching is a starts with match, rather than a contains (due to # of users)
  • Stack Overflow's meta is meta.SO, which is a fully fledged site
    • all other network sites have a "proper" meta, with synced accounts
    • ... except Stack Apps, which has no meta at all
  • Some of the social sharing stuff is suppressed
    • This is also true of all metas, SU, and SF
  • Ads are served
    • This is true of SU and SF too

Can't think of any other differences off the top of my head.

*stackexchange.com and Area 51 are different code bases though.

One more: different question sorting algorithm for the main page. –  Tadeusz A. Kadłubowski Jan 23 '11 at 20:16

@Tadeusz - that's the difference between the interesting tab and the active tab, bullet #1. –  Kevin Montrose Jan 23 '11 at 20:18
