Google+ is an interest-based social network owned and operated by Google. Features include the ability to post photos and status updates to the stream or interest based communities, group different types of relationships (rather than simply "friends") into Circles, a multi-person instant messaging, text and video chat called Hangouts, events, location tagging, and the ability to edit and upload photos to private cloud-based albums.
Since Gmail users get connected to Google+ directly through their email account, Google+ has a lot of users, but relatively lower engagement comparing to other traditional social network platforms. Brown primarily uses Google+ for Hangouts and to amplify Google search results.
Brown University reposts content from Twitter, Instagram and Facebook on Google+, to share campus news and photos.
