An ex-Microsoft employee who now works for Google started a blog which has interestingly been removed from the Google index.
From various sources including SEO Roundtable
An interesting post from one of the blog posts that was removed includes a comment after attending the Google sales conference:
“so after the interesting financials, the products team gave presentations reviewing product performance in 2004 and giving sneak peeks of the products we’ll unveil in 2005. if you guys thought gmail and google groups were cool, you ain’t seen nothing yet! ”
