Does anyone have a clue what the difference in the sort / ordering of the questions is when you click on 'Top Questions' and 'Questions' - they look the same to me.

And then when I 'sort' with the right hand sub-tabs on the 'Questions' or the 'Unanswered' pages, what's the difference between 'newest' and 'active'?

I expected to be able to sort by 'views' (move top viewed Q&A to top)
I expected to be able to sort by 'answers' (most answered to the top)

On the actual question, I'd expect the most 'voted' answer to move to the top of the list, but it doesn't, so as i scroll down, the higher voted answers 'MAY' be at the bottom.

I'm missing the subtleties of sorting/ordering...

Can anyone fill me in?
