Our timing was good, our choice of product categories — books — was a very good choice. And we did a lot of analysis on that to pick that category as the first best category for e-commerce online, but there were no guarantees that that was a good category. At the time we launched this business it wasn’t even crystal clear that the technology would improve fast enough that ordinary people — non-computer people — would even want to bother with this technology. So that was good luck. So there are a whole bunch of things that have to sort of align to make it work.
