Hate to say it, I agree.
I love seeing pics of a nice dish, but find it a real distraction when folks with whom I am dining take pics of every morsel as it arrives. For me, it's about the food, not the pics of the food.
I'm also the guy who is VERY moderate when taking pics on vaca... I'd rather see Tuscany with my eyeballs rather than through the lens of my camera. Call me crazy.
