Google has unleashed Google+ on the world, now completely unfettered by its earlier requirement to join via invitation. For its debut, Google has added a slew of enhancements as well. Chief among them is the addition of a search box, which allows people to search for content or other people within the Plus network. It has also launched Hangouts for mobile devices, with support currently offered for devices with front-facing cameras running Android 2.3 and up. Another addition is Hangouts On Air, an option for users who want to broadcast and record their sessions.
