Is there a usefulness in having a hover function for a question - to see the question in a hover box, to avoid clicking on it to see what it's about? I feel some questions generate a 'hot topic' status simply because of this 'need to click' to see what on earth is going on... who'd ask such a thing... why?!
Often such questions get closed, but only after 2000 clicks! They are probably off-topic anyway.
