Youre probably right Sean, in a way your post proves my point about google though. They keep changing what is relevant for search criteria and what and/or how it works. WHY? To keep you on your toes. Its silly really, why do they want you to be ever alert with your finger on the pulse continually updating your website, checking word relevance and the balance of meta tag references to those on the page.
If google had invented the motor car they wouldnt have included the wheel.
