We are reunifying all our products (Stackoverflow.com, Stack Exchange network sites, Stack Overflow for Enterprise and now Stack Overflow for Teams) around a coherent design and single codebase.
Absent from this list is Area 51. Area 51 is an important area where all new sites are created - something critical to your business model.
As it stands, the site is very outdated - will it be included in the new codebase as well?
Notice the old navigation bar, the lack of global log on, a highly custom layout etc.
