Mike,
I very much appreciate your taking the time to make this first order approximation.
What I find interesting is that the $.80 per reader is well with the range of what might be able to support with advertising and/or selling the identification of the reader's interest (i.e. selling his name), depending on the specificity of the identification.
But I suspect that books are likely to be quickly supplanted by electronic media. A magazine or article might be more likely-- particulalry something continuously updated.
Regards,
John
