Apparently it is now important that you name your Google Circles with meaningful names. They actually affect peoples' rankings. So rather than having entries of "friends" and "family" - think about what the people do. Have entries for "web content writer" and "kindle authors" and "technical professional" and "graphic designer".
So let's all help each other out, with links and circles!
Post your profile link here, and a circle name or two that relates to what you do.
For example my link would be
https://plus.google.com/109263407720411193859/postsand good circles to put me in would be
Kindle Authors
Web Content Writer
Together we'll help each other succeed!
