One thing is for certain, wherever you have sharks you'll always have those who want to interact with them.
Recently folks in Australia decided to get into the interaction game and shot some amazing video. You cannot miss the sequence starting at 1.20 - it is pretty stuff.
Unfortunately the broader world does not seem to share the joys of these interactions (see You Tube comments). Perhaps when framed by the media as this clip was recently, the natural comment blow back is to be expected.
