Quang-Tuan Luong did a survey about who is actually selling prints on the net a while back. I forget whether it is on largeformatphotography.info or on the LF forum, currently at photo.net.
My photo site is intentionally short on information. I just put it up so that people who are curious about my photo work can see what I do. If they are interested in buying prints or something else, they can email me.
