The world's teenage population can pontificate from a new digital platform, now that Google+ has decided to open its doors to high schoolers. Google+ VP Bradley Horowitz made the announcement yesterday, confirming that anyone old enough to own a Google account can now join the social network. In most countries, that applies to anyone older than 13 (previously, Google+ had been restricted to the 18-and-over crowd). This expansion also introduces a new set of privacy controls for younger users, who will be warned every time they try to publish a public post, and can only be contacted by those in their immediate circles. If a teen joins a Hangout, moreover, he or she will only be able to receive audio and video from those in his or her circles. Find more at the link below.
