A poll would've been nice.
That said, I carry concealed despite the fact that I'm allowed to OC in my state.
I really don't see the point of open carrying.
Here are a few of the reasons why I choose not to OC: 1) You lose the element of surprise; 2) You draw unnecessary attention to yourself (i.e., you scare the "sheeple" who know nothing about gun laws); 3) You expose yourself to potential weapon retention problems (e.g., a threat sees your pistol prominently displayed on the hip and disarms you from behind).
I suppose a few advantages of OC are: 1) Comfort; 2) Quicker draw stroke.
Why do you OC, OP?
