Perhaps I am reading the post title incorrectly. What DID they really clone? Oh, title like "created a Q&A site engine using Redis and jQuery, and styled it to look a bit like StackOverflow, whoop-de-doo" is not catchy. Q&A sites are not about the code, they are about the people, asking and answering the questions. It's nothing without the community.
