With an amazingly active community on Google+, there’s still a significant number of ghost-town profiles, where countless people have received the coveted invite, taken one confused look, and promptly turned around never to be seen again. So how do you sift through all the empty profiles, to find the really interesting people worth following?

There’s actually quite a few ways you can find interesting people to circle on Google+, based on location, type of posts, occupation and more. Whether it’s using third party sites, or checking out what’s going on right there on Google+, you’d be surprised at just how easy it is to find people posting interesting and valuable information on Google+.

Circle Sundays

Brian Rose came up with the idea of bring Twitter’s Follow Fridays to Google+. Of course, to set them apart from their Twitter counterparts, they were called Circle Sundays. If you want to search for people’s recommendations, go to Google Plus Search and perform a search.

What’s great about Circle Sundays on Google+ is that users really have a great opportunity to go into detail explaining why they’re making the recommendation. Follow Fridays on Twitter quickly degenerated into lists of names, with no reasons given as to why the recommendations were being made, and maybe it was to be expected with the 140 character limit. On Google+, there’s simply no excuse. Christina Trapolino is a great example of how Circle Sundays should be done.

Recommended Users

Recommended Users is a handpicked list of users worth circling on Google+. The site really strives to provide a list of only the best users worth following on the social network. What makes it really useful is the fact that the lists are divided into over 20 categories, so if you want to know which photographers, bloggers, podcasters, journalists, web developers and angel investors to follow on Google+, check out the site.

Google+ Counter

If you want to find interesting lists of people worth circling, or even curate a list of your own, Google+ Counter is the place to go.

Women of Google+

Much has been said about the incredibly unbalanced ratio of men to women on Google+, but there’s no denying how many fascinating and interesting women there are on Google+ that are worth following.
