a website that allows collaborative editing of its content and structure by its users.
StackOverflow is a website that allows users to edit the content of questions, answers, and tags. It also allows users to write new questions, new answers, and close existing questions and answers. How is that "nothing like a wiki"?In his post here, he kind of directly writes that SO is not like a wiki.

"Because unlike wikis.."
When most people think "wiki", seeing answers before questions is certainly a common characteristic they could assign to the concept, but it's not what makes it a "wiki".
I could design a wiki that was text-only and say, "unlike wikis, we don't present photos", but that wouldn't make it not-a-wiki.
