NetGoonie ... thanks for the checklist. No worries about the house in the Tropics, I'm already closer than I want to be now.
Ramster ... yes, that was exactly why I was asking for some input here. I knew that we didn't have a critical piece of info if we wanted to use that formula. So I thought I'd come ask if there were some other ways to put a value on them.
Like you said, I know that 25K surfers a day looking for porn/stories is worth something. I'm trying to figure out some way to get at that number with only the traffic figures to work with.
