Google's social service boasts 343 million active users.
Google+ has surpassed Twitter to become the world's second leading social network, with Facebook maintaining its market leader position.
GlobalWebIndex revealed the usage figures with a report showing a change in usage from localized social platforms to global social networks including Facebook, Google+ and Twitter.
Google+ now boasts 343 million active users, while Twitter has slightly under 300 million active users. However, the latter experienced the strongest growth with 40 percent across 31 markets, which accounts for around 90 percent of the world's internet users.
Twenty one percent of worldwide internet users utilize Twitter, while 51 percent use Facebook and Google+ boasts a 25 percent share. YouTube, which is owned by Google itself, is tied with Twitter with 21 percent.
GWI said Mark Zuckerberg's website has not been affected by "Facebook fatigue" and saturation in order to achieve around a 33 percent growth margin. Google+, meanwhile, grew by 27 percent.
Facebook announced during October of 2012 that it has surpassed one billion monthly active members. In December, Google+ reached 500 million registered users and 135 million active members.
Although this was before the announcement of Graph Search, Google co-founder and current CEO Larry Page recently said that Facebook is "doing a really bad job on their products," and stated that Google+ can coexist with Facebook.
Page's comments were preceded by Google+'s VP of product stressing that Facebook is a social network of the past and that it's "pissing users off" due to its intrusive advertisements.

IMHO that is the beauty of it. It is always there, does its thing seamlessly and in the background. And when you need it (like if your phone goes missing, or you feel like sharing something with someone quickly without having to search on your phone) it is a breeze. IMHO, it is a social network done right.
(Hey Tom's, how about saving my typed comment/auto posting it when being forced to re-login? I'm sick of having to retype everything just because I switched wifi networks and you don't recognize my PC anymore.)
Overall, I do prefer Google+'s layout, hope it catches on.
I went there and it's game trailers everything is apparently I did something with them on Google plus once. Some people that I know why tried to use Google plus wrote some things and it's there.
I just don't get the appeal of Google Plustek anybody outside of it being a glorified RSS feed. I have Google talk, it tells me when I get a new email, I try and set everything that I do up so I get a new email whenever something is responded to whenever somebody posts something that I want to keep up with I use my email for that. Was it so hard for people to track others through email that they had to make social websites just for this. Community social websites offer you a webpage that you could customize be whatever you want and a was somewhat simple to do I can understand people liking that crap but Facebook Google plus twitter I don't understand the use of them.
So can somebody please tell me what the hell use a social network is I really want to know, and so everyone knows I'm 25 I should be in the demographic for being addicted to this crap.
