Google+ provides a viable alternative to Facebook where people can store and share their photos, thoughts, locations, and more. You also get group messaging as well as audio and video conferencing.
Easy log-in: If you have any other Google app installed on your device, and you've already logged in to it, Google+ will automatically detect it and set you up.
Automatic photos backup: If you enable the feature, every photo you take will be uploaded to a private gallery on Google+, creating a reliable backup and allowing you to delete the photo from your device -- thus reclaiming storage space.
Amazing interface: Google+ features an amazingly fluid and playful interface. The designers have struck a great balance between form and function, allowing you to get to most common functions quickly while making the experience very pleasant.
Modular experience: In order to keep the app fast and responsive, some elements of Google+, such as Hangouts, have been separated into their own apps.
If you're tired of Facebook, and you find yourself using more and more of Google's services, a switch to Google+ may be tempting. However, since a social network centers around people, you need to get your friends to make the jump as well, which makes such a transition a lot harder.
