I ask the question because I'm curious to know what kind of background from a technical standpoint does it take to create, manage, scale something like SE. Are there a lot of engineers drawing UML diagrams, programmers pounding away at their keyboards, a bunch of late nights for everybody, etc.
Uh, are you seriously asking what the education background is of the Stack Exchange developers?
Our core development team is: Jarrod, Sam, Marc, Emmett, Geoff, Nick, Ben, Kevin, and Rebecca (sometimes). All of them have at least a bachelor's degree from accredited universities. Many of them bring with them years of experience, either at large corporations (pharmaceuticals conglomerates, Microsoft, etc.) or in open source / personal projects prior to joining SE. A number of them were super-major-top users on SO when we pulled them onto the team.
I'm closing this question because, seriously, anything you need to know about our dev team you can find out from http://stackexchange.com/about/team and by checking out their Stack Overflow profiles.
