Nothing livens the day like a blurry screen grab of some Javascript, especially when it hints at the ghostly form of a social networking tool that doesn't officially exist. The code was spotted hiding in plain sight at Google Profiles by Austrian blogger Florian Rohrweck, who fortunately enjoys browsing computer-speak more than playing in the park. Rohrweck noticed the word "circles" used repeatedly in the context of people adding and maintaining groups of contacts, and made the connection to the Google Circles social networking platform that was feverishly rumored and then vehemently denied earlier this year (a saga fully recapped at the More Coverage link). It's impossible to know whether these few lines of code represent a forthcoming service, another social layer on top of existing services, or just pure experimentation on the part of Google devs. In any case, the circular references have apparently now been zapped, leaving us with nothing more than that screen grab -- oh yeah, and Facebook.
