This question already has an answer here:
Is there an option to keep the reputation blurred out when you're on stackoverflow? I mean, it stays blurred or hidden with an overlay until you hover on it or click it. Because I often have to pair-program or show some stackoverflow answers to my peers and since the header is sticky on top, I have often heard remarks about my reputation. Would be nice to have a feature to have the reputation revealed only when you interact with it.
