At my company the Managing Director reads prune all the time. It was him that got me into it although he's probably regretting it now!
Far from hiding their interest, whenever there's a thread that's about us you will always find someone around the crew room with a print-out of it.
Remember that to those who haven't discovered computers yet there is nothing more boring and us pruners are a bunch of nerds.
What they don't know is that resistance is futile and they will all be assimilated in the end!
