Anyone know what weight Google assigns to Twitter profiles? I'm assuming junky newly created accounts aren't assigned any weight, but for long term influential accounts with lots of followers, what PR does G assign? Do they use things like Klout to measure influence or have inhouse metrics of their own? Yes, I know Goog is generally v secretive about their algorithm, but perhaps there is some info out there that I am not aware of, or Matt Cutts covered it on his blog, or such. Thanks!
