YouTube - Google+ Integration

Google integrates YouTube with Google+. All users can switch their YouTube names to Google+ profile name. 

Next time when you sign in to YouTube (Sign in directly to YouTube, not just clicking YouTube link from Gmail or any other Google product that you are logged in) it will prompt you to use your full name on the site. This feature will not change the link to your channel, and you can use your current username for login.

If you dont like to switch, you can continue with your current YouTube name also. 

Once you complete switching process, you YouTube account will start showing Google+ notification, and Share options on the top, just like Google and Gmail. You can directly share the current playing video to Google+ just by clicking the G+ Share button in YouTube.
