I agree with skyweb - content and constantly growing content is more important to the INFORMATION HOUND (g).
and with Tedster, - the signals could be very mixed and confusing to G.
Some people opt (as do we in certain cases) mask Identity.
for g to figure out how to devalue that would be a real stretch.
whois masking may indeed be of value next year. the History of domain ownership will always be easily accessible to g though. so unless you start a domain with whois masking, it will always be there (domain tools)
