Please forgive me for asking multiple questions at once, but I think these are all related to a confusing choice of main buttons on SO.
One thing that has always bothered me about the SO user interface is the "questions" button and the "unanswered" button on the main interface. Aren't unanswered questions just a subset of all total questions? Why does it warrant a totally different top level choice when it could just be a remembered or default tab choice within questions?
And why are the tab choices under questions different than the tab choices under unanswered? Aren't both just showing a list of questions? Why am I allowed to view "my tags" under unanswered, but not under "questions"? I want to be able to see answered questions that match my interests, not just unanswered questions.
Maybe I'm misunderstanding something fundamental. Maybe there is a logical explanation.
