It's hard to believe that Google+, the search giant's answer to Facebook, is two years old. Google continues to tinker with its social media platform, and its latest efforts are noteworthy. For instance, Google+'s new multi-column layout, which varies from one to three columns, depending on the resolution and orientation (landscape or portrait) of your device, is visually appealing. And Google+ now scans posts and automatically adds hashtags to your stream, making it easier to browse related content. Granted, these aren't the kinds of jaw-droppers that will create a mass exodus from Facebook, but Google+ is certainly becoming an innovative place to hang.
