A long thread has developed over at High rankings Forums about the subject of marketing testing with a website. The idea of using methods like A/B testing has long been promoted by groundbreaking paid search leaders such as Lee Mills and other early adopters of measurement technology. Many of the most reliable paid search firms of the day are "sophisticated," classified as such by Jupiter in 2004 and introduced by Chris Sherman at the SEW Blog.

in fear of being "banned" by the search engines that they're afraid to sneeze around their computers for fear of offending the Search Engine Gods.
The thread is one of those rare ones that goes (so far) 3 pages without actually getting boring.
