It has been just over two weeks since the Google+ social network was launched. While it is still in a beta invite-only period, Google's new social networking platform has created a buzz amassing more than 10 million users. According to recent reports, the most followed person on Google+ is none other than Facebook CEO Mark Zuckerberg.

If the news of Zuckerberg as the most followed person on Google+ amused you a lot, here is another dose - not just Zuck, there are at least 62 Facebook employees, who have signed up for Google+. According to a recent count and unofficial list compiled by Huffington Post Senior Editor Craig Kanalley, the 62 Facebook employees on the new social service include Chief Operating Officer Sheryl Sandberg and Chief Technology Officer Bret Taylor.

Since Google's new social network is intended as a rival to Facebook, it does make sense that Facebook's team wants to check out its competition has to offer. It's difficult to say right away whether Google+ can overturn Facebook, but its massive growth of more than 10 million new users in less than one month is enough to raise a few eyebrows.

Although, there has not been any confirmation on whether the accounts of the Facebook employees are real, a look at their circles and connections indicate that they are legitimate, Slash Gear reported.

Meanwhile, LinkedIn CEO Jeff Weiner has a completely different take on Google+. When asked, at a Churchill Club event Santa Clara, Calif., on Monday, if there is any limit to the number of social networks that can successfully exist, Weiner said there is a limit and forecast the defeat of Google+ in a battle against Facebook, Computerworld reported.

Nobody has any free time, Business Insider quoted Weiner as saying. Unlike social platforms and TV, which can co-exist, you don't see people using Twitter while they're using Facebook, or using Facebook while they're using LinkedIn.

Weiner said, according to Business Insider, while people use LinkedIn and Facebook for their professional lives and for socializing with family and friends respectively, Twitter gives people a way to share their thoughts with a broad audience. But the emergence of Google+ is creating imbalance in that mix.
