The folks over at Windows Live Spaces just crunched some ComScore worldwide numbers. Their headline was "Windows Live Spaces at a Crossroads", but I think my headline fits their graphs better.
According to them, Blogger did140,000,000 worldwide unique visitors in September, and has been on a tear since June. Nice! And to all those Blogger users, thank you!
Of course, whether Blogger is a "Social Networking" site depends on your definitions; Dare wants to disqualify the front runner. Me? I think 140 million people can speak for themselves.
