Google+ just launched a brand new sign-in system for third party sites that sounds a whole lot like. . . . okay, I won’t say it, but we’re all going to think it anyway. This new sign-in system allows anyone with a Google account (so. . . all but five people on the internet) to login to a third party site with one click (several clicks the first time, but one after that). But it’s more than just an easy button, the new Google+ sign-in system is the next step in social sharing.
The first time you use the sign-in on a site, you’ll be asked to login to your Google account, then choose your permissions.
