When did Stack Overflow first go live?
Jeff Atwood announced the Stack Overflow private beta on July 31, 2008. It went public some time afterwards. The Stack Overflow blog was created long before as a communication method between Jeff Atwood and Joel Spolsky and the audience and as a hosting ground for their podcasts.
