I have been using ZocDoc. Not sure our exact numbers, but probably at about the break-even point. I think it does attract drug seekers, but my ZocDoc profile specifically states: "We do not prescribe narcotic medications but we can make recommendations to your Primary Care Physician." So I think this has helped to keep most of them away. Also my office staff is good at screening out the drug seekers so that has not been a problem for me. As per Pacman27, the reviews have been mostly positive for me, with an overall 5 star rating, so I think that helps, in terms of building up online reputation/presence. Otherwise, I would not expect too much from it either. It also may depend on where you practice and how much patients in your area actually use ZocDoc. We checked with a pain physician colleague in the area before signing on, and his experience was exactly the same as what we have experienced so far.
