The purpose of Stack Overflow is not to serve the people who ask the questions, that's just a happy side-effect. The purpose is to create a resource to serve future Googlers.

There are less broadly-interesting new questions in areas of established technology, but that's fine: there's less need for new questions in areas that the site already serves well. Stack Overflow is not having any trouble getting good questions about new technology as it becomes out.
