you can always find google trying new things… challenging the fields they are not good at…
and this time I just find there social circle idea~ seemed cool as a search instruction

as you search, they try to find what your friends said about it on twitter or there blog…(ok this time it’s me myself…=_=)

I follow the link and find google just use the link submitted by the users to the google profile as the information sources… It’s just smart, and included from blog, twitter, flickr, all the way to douban and xiaonei…

as facebook beating google to become the most visited web site, google is definitely finding some way to fight back… I just enjoy the war ;->
