Google seems to be finally realizing that people do not easily understand the concept of circles.
They have tried making this feature easier to understand by renaming it Find People in a new update that has been rolled out on Google+.
Instead of the complicated user interface before, users now get suggestions from people they are already communicating with on email.
They also get to fill in quick details about their education and work life to get suggestions from those fields.
Google developer Sean Purcell spoke about this update:
For starters, the Circles icon in the app ribbon is now labeled Find People. Click through and you’ll find a new page with a list of people you might want to add. We’ll show you people you’re already talking to on Gmail and other Google products at the top of the page. To get even more suggestions, it’s easy to search by your school, workplace, or other email accounts.
If you want to organize the people you’ve added a bit further, you can always click the “Your circles” button at the top of the page. From there you can use the circle editor to see all of your circles and decide who belongs in each one.
