After its launch, Google+ attracted a lot of attention. During its first weeks, many people unsuccessfully waited for an invitation that allowed them to join the new social bandwagon, that some analysts pointed as a potential threat to Facebook.
Nevertheless, it seems that most early users from Google+ came from the techie and nerd communities.
You just have to take a look at the top of the list of Google+ users with most followers to reach that conclusion: instead of Lady Gaga or Justin Bieber, there we will find Mark Zuckerberg, Larry Page and Sergei Brin.
This data comes from Google+ Statistics Website, maintained by Boris Veldhuijzen van Zanten, co-founder of Twitter Counter, which also brings some interesting information on the male/female ratio of Google+ users: men account for 88% of the user base, against only 10% of women (and 2% of “other”). That’s a HUGE difference, indeed.
