It's nice of Matt to find counterexamples to your arguments. But you should know that pointing out that you use circular logic is enough to show that your argument is not valid (in other words, no counterexample is really needed). Now, this doesn't necessarily say anything about whether this company is Amazon or not, but it does show that your proof, that there is no way this is Amazon, does not hold water. (The first two quoted lines are my own interpretation, others are quotes.) "Amazon is a big company. Big companies don't make amateur mistakes. That's why they're big." "Therefore, Amazon doesn't make amateur mistakes." http://en.wikipedia.org/wiki/Begging_the_question http://en.wikipedia.org/wiki/Begging_the_question (Repeating this type of logic over and over is...) http://atheism.about.com/od/logicalflawsinreasoning/a/repetition.htm http://atheism.about.com/od/logicalflawsinreasoning/a/repeti... "The checkout path is the most important part of a site that sells consumer products, the people you lose here are ready to buy: If you lose them during the process it's money right out the window. For this reason it's the most optimised part of any serious retail site." http://www.csun.edu/~dgw61315/fallacies.html#Red%20herring http://www.csun.edu/~dgw61315/fallacies.html#Red%20herring "This is a pretty standard trap, and any usability professional will know this." http://www.csun.edu/~dgw61315/fallacies.html#Argumentum%20ad%20populum http://www.csun.edu/~dgw61315/fallacies.html#Argumentum%20ad... (Continuing to post more arguments feeling you must be right since no evidence has been provided to the contrary, is...) http://philosophy.lander.edu/logic/ignorance.html http://philosophy.lander.edu/logic/ignorance.html "The thought that they somehow didn't do so on the checkout path, the most important part of the site, is pretty far fetched." http://en.wikipedia.org/wiki/Straw_man http://en.wikipedia.org/wiki/Straw_man (nobody said they thought Amazon absolutely decided to skip usability testing of checkout functionality. Also, for example, they could have tried but did not think of changing it, or ran out of good subjects who hadn't already used Amazon's checkout page, bad selection of candidates, poor interpretation of results from the split tests, or had lots of bureaucracy or competing work or designs of checkout incompatible with such changes, human error, that this looks easy in retrospect but not something they thought of at the time, person in charge of that being complacent, etc.)
