TechCrunch posted an screenshot, that looks to be a picture of Google's latest social foray "Google Me", or "Emerald Sea", or "Google +1".
"As you can see, it's a toolbar that exists along the top of Google's properties -- in this case, Google News. There's a Share button, a place for a Google account icon, and a Google username. Next to it, is a numerical count -- it's not clear what this's for. And next is an options menu.
Also note the big red "CONFIDENTIAL!" label. The person who shared this clearly wasn't supposed to.
Another important thing: the "Loop" area in the left side toolbar links. "loop", seems to be Google's word for "groups". Loop is also an iPhone app in testing is being called.
Here's a repsonse from Google:
"We're always experimenting with new ways to improve our products, and we have already confirmed that we are focused on incorporating social elements across Google. But we have nothing new to announce at this time."
