Well, we say ‘popular’ – we should clarify that a lot of people signing up to Google’s social network may only be hazily aware that they’re doing it. The Wall Street Journal notes that “people who create an account to use Gmail, YouTube and other Google services—including the Zagat restaurant-review website—are also being set up with public Google+ pages that can be viewed by anyone online” – an initiative thought to come from CEO Larry Page himself, as he seeks to build Google+ into a genuine Facebook rival. Cue stories like the user who signed up for Google+ on his phone to create a private photos folder, but then saw a review he’d written on the Google Play store appear on his profile. “Google+ is Google,” Google’s Bradley Horowitz tells the WSJ. “The entry points to Google+ are many, and the integrations are more every day.” By some metrics – 235m people using Google+ features across Google’s sites a month – the strategy might be said to be working, but if many of those users don’t realise they’re actively engaged with Google+, marketers may remain cautious.
