A platform is only as good as the people who are on it, right? While Google+ does a pretty good job of surfacing cool people to follow through its suggested users list, shared Circles are an even better way to find people to engage with.

Once in a while I’ll see someone that I follow share one of these Circles, and it usually has some type of theme, be it photography, technology or entertainment.

One user decided that it would be a good idea to put together a massive Google spreadsheet of Google+ shared Circles, neatly categorized for your enjoyment:

Along with the Circle name, you’ll find who authored it, as well as links to the Circle itself. It’s a huge help for those of us who want to jump right into the Google+ destination site but don’t have anyone interesting to follow.

Whether you’re interested in sports, celebs, education or business, you’re sure to find a Circle that nabs your interest.

No more excuses, get to following.
