When I go to the "Unanswered" section of Stackoverflow most of the listed questions are answered. Is this right?
The definition of unanswered, at least on StackOverflow, is:
A question in which no answers have been up voted.
Or, taken directly from the sidebar:
4,529 questions with no upvoted answers.
This means that there might be 50 or so answers to a question, but if none of them were up voted, it is technically an unanswered question.
