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,
Why does SO have such a format unlike the rest?
Are there any other sites that have a unique upper interface?
