What I do know is that my viewers fall into 3 categories. Celebutard followers, car nuts and English Rose fans. Also people like to look at the films from my MRI a lot - go figure.
What I do learn comes from comments and favoriting of images in my sets. That information becomes invaluable in helping me determine which images are framed and sorted for shows and which are simply sleeved for future sales from the files.
I know I can count on 200 views a day more or less. I am found from a variety of sources. Most are google searches, some are from bookmarks, others are from my flickr friends who watch my stuff on an RSS Feed.
Nice to know that some of my images can stop people in their tracks and go hmmmm...
