re: Google In 2013: 11 Predictions
"Google says Google+ has 400 million registered users. Okay, so many of those are compulsory members, but Google insists it has 100 million active monthly users."
@Thomas, Google+ has 500 million members, 235 million active users across Google (as Facebook has 1 billion) and 135 million in the stream and mobile app only. Nice read and seems really accurate though.
My quick predictions:
1. Google will merge the Chrome Web Store with Google Play Store - one store for the whole Google ecosystem.
2. Google will launch 'Google Play Games', a game center which will be the unification of Google+ Games, Hangouts Games, Android Games and Chrome Web Store Games.
3. Google+ will have 1 billion members and 500 million active users.
