Facebook CEO goes coy on Google+

Facebook CEO Mark Zukerberg seems to have suddenly gone coy on Google +, Google's latest challenge to Facebook. The founder of the world's no. 1 social networking site Facebook recently hit headlines for being the most popular person on Google+.

According to Web reports, Zuckerberg has apparently changed his privacy settings so that they no longer display how many people follow him or how many people he has placed in Circles on the new social network. Circles are groups of friends on Google+.

Incidentally, he is not the only high-profile corporate honcho to have opted to go private on Google +. Google founders Larry Page and Sergey Brin reportedly too seem to have hit the privacy button, hiding how many friends and followers they have on Google+.

The trio have since then fallen off a ranking of the 100 most popular people on the new social network.

The unofficial top-100 list is compiled by an Amsterdam-based team of programmers on a site called Google+ Statistics. The same group is also said to track user popularity on Twitter through Twitter Counter.
