A very sharp and experienced developer named Eric wrote the first version of similarities that made it out to the Amazon website. It was great working with Eric. I learned much from him over the years.
The first version of similarities was quite popular. But it had a problem, the Harry Potter problem.
Oh, yes, Harry Potter. Harry Potter is a runaway bestseller. Kids buy it. Adults buy it. Everyone buys it.
So, take a book, any book. If you look at all the customers who bought that book, then look at what other books they bought, rest assured, most of them have bought Harry Potter.
