I haven't bought anything from amazon.com in a long time. I don't expect I ever will. I refuse to support an organization which continues to exploit the USPTO in obviously idiotic ways. Today I saw a news report entitled Has Jeff Bezos Patented E-Mail Discussion Groups?:

First he received a patent for 1-Click e-commerce. Now he has one for e-mail discussion groups. Last Tuesday, February, 25, the US Patent and Trademark Office issued a new patent to Jeff Bezos, the CEO of online retailer Amazon.com, granting him exclusive rights to "a method and system for conducting an electronic discussion relating to a topic. As was the case when he and three other Amazon executives patented the company's 1-Click ordering system, Bezos has gained control of a technology that may not seem particularly innovative to the everyday Internet user.

Or anyone else, for crying out loud.
