If you look at the Lew Rockwell homepage you will see that they have an Alexa referral box on it. The Alexa rating system works only for Browsers with the Alexa Toolbar installed. The Alexa spyware collects surfing data on those browsers with the toolbar installed. Currently the Toolbar only works with Microsoft Internet Explorer.Same talking points . . . If you are an employee or contributor or flunky at LR.com, you should at least have the honesty to admit it.Lew Rockwell hypes the Alexa Rating by featuring it on his hompage and often mentioning his ratings as the example you have linked. His users are more likely to use the Tool Bar offered by Alexa if for no other reason than they are aware it exists, which would not be typically true of the other sites he shows in the comparisons he listed.
Alexa ratings my be relevant comparisons for sites that do not make prominant reference to Alexa and thereby Skew the ratings upward. Also, I don't think he is doing his readers any favors by leading them to a toolbar that loads spyware on their computers.
