It seems one of the biggest business issues is site visitor perception. I have a couple questions please.

What's your opt-rate rate so far out of the sites that have shown this option?

do you have any real data regarding hidden cost to a site visitor? like power consumption A/B testing or something?

The opt out rate has been close to 0, but (in all fairness) that has been due to the way websites choose to display it.

A standard for how to display might be called for, perhaps?
