If you want to find people who are in your neck of the woods, from your Alma Mater, or from a specific industry, FindPeopleOnPlus is a great source for finding interesting people on Google+.

FindPeopleOnPlus also has a great section of users waiting to be discovered, based on specific categories. The site has special Canada, India and UK-specific versions. The site also gives you a convenient way to see which of your Twitter friends and followers are already on Google+.

recruiters and hiring managers are able to target and find the right job candidates for their openings.

"Some 25,000 users in their sample identify themselves as single, versus 19,000 married and 12,000 in a relationship. The vast majority of the million users sampled don't say what they are."

Google+ to this point might just be showing people who are in your network but this service will help you find interesting people to follow, maybe hire your next great employee or perhaps just find someone to carpool with.

A separate site, Find People On Plus, offers an intuitive search index of all Google+ users. Searchable categories include relationship, gender, looking for, following, followers, occupation, on Twitter, on Facebook, country, state and city.

Here, you can not only search for people by name, but you can also search by profession, location, relationship status, gender, education, employer, occupation and more, which makes growing your network and tailoring it to your needs a lot easier.
