Looking at most sites, I noticed something a bit weird. Stack Overflow has a different layout for their upper interface (which personally I find unique and easy to use).

On most of the sites I see:

| SE logo & Sites dropdown | Inbox | Achievements | --- | Profile | Help | Searchbar |
| Sitename | --- | Questions, Tags, Users, Badges, Unanswered | Ask Question |

On Stack Overflow:

| SO logo | Questions etc. | Searchbar | Profile | Achievements | Inbox | Help | Sites dropdown |

I have two questions,

  1. Why does SO have such a format unlike the rest?

  2. Are there any other sites that have a unique upper interface?

  • Stack Overflow hasn't had the new top-bar for long. It's eventually supposed to be deployed/mirrored on other sites, but the team has a few more things to sort out before they do that.

    See Top Navigation Update and the top-bar tag on Meta Stack Overflow.

Stack Overflow's unique navigation bar is an updated interface which began testing on February 13, 2017. This updated interface is currently only available on Stack Overflow, but will soon be applied to the entire Stack Exchange network.

For a detailed explanation, see Top Navigation Update on Meta Stack Overflow and How Stack Overflow Redesigned the Top Navigation on the Stack Overflow blog.

Top bar updates are coming to the rest of the Stack Exchange network in the next couple weeks (Sept 2017). Check the details here.
