That's interesting. I know some feeders have been bitten, but always assumed observers might have been too. Might I inquire as to the source of your information? Shark feedings I believe count as "provoked attacks" on the shark attack website, so they're not included with the normal statistics. I'd be quite keen on getting the stats for shark feeding injuries.
Oh yeah, forgot to put in my opinion for the poll. I believe shark feeding is bad, BUT I really LOVED participating in them. I'd argue that lots of people are against feeding, but these same people would almost certainly attend one if they hadn't previously.
I'm also an "evil ecologist", so that makes me biased towards the wildlife.
