That's Latin for "cool"
tensen said:I think the model is a little skewed. 90 days sales window is silly to think of with PDFs. I think we have 3 year old products that are still selling more a month than what they give as low sales figures for new products. This is because people are thinking on the low end, and not putting sufficient time and effort into products. If they realize they can do better sales, maybe they won't just be satisfied with low numbers, and actually take time and polish their products.
That and the more serious publishers can generate interest in old product with new product. If someone decides to buy ProductX-2004 and then goes to the download site to discover ProductY-2002, the consumer might become interested in the older book. However, a first time publisher by definition doesn't have that older product for sale.
Now, I am clearly talking out my posterior as I am not a publisher or an industry expert. I'm just a fanboy. But if I was a publisher, I would take that 90 day window seriously and think about what I wanted to follow up with for the next quarter. But, again, I have nothing to back that assumption up with and I will happily waddle off into the sunset given even anecdotal evidence to the contrary.
