+ - Google+ is a ghost town, study says->

Submitted by zacharye
zacharye (2330148) writes "Google’s emerging social network Google+ may boast big user numbers, but a new study suggests that social activity and user engagement are anything but impressive. Intended to give Google a stronger grip on the massive amount of data shared by users on social networks, Google’s answer to Facebook opened its doors to the public last September.

"Moni Bidin says he’s not sure whether dark matter exists or not. But he says that his team’s survey is the most comprehensive of its type ever done, and the puzzling results must be reckoned with. 'We don’t have a good comprehension of what is going on,' he says."

"As an example, Newberg notes that the researchers assumed that the group of stars they examined were smoothly distributed above and below the plane of the Milky Way. But if the distribution turns out to be lumpier, as is the case for stars in the outer parts of the galaxy, then the resulting calculations of dark matter density could be incorrect.

Flynn agrees that there are a number of ways that the method employed by Moni Bidin and his co-authors 'could get it wrong.'""
