Why is it that many of the questions that appear when a user clicks "Unanswered" from the main page have answers?
What is the unanswered catagory? Is it questions without an accepted answer?
Questions that have no (net) up-voted answers are considered unanswered (unless an answer has been accepted without up-votes).
I know I've seen a better explanation than this one, but I haven't found it yet.
