Google+ is presented as a platform that combines features of Facebook and Twitter, described as a 'connection engine' with a cleaner interface for sharing data. Higher engagement rates are noted, particularly with commenting and resharing, alongside tools like Google+ Hangouts and Sparks for content discovery. Key features include customizable circles for sharing and various keyboard shortcuts to enhance user navigation.
