Google+ Recommendations by industry
RecommendedUsers.com is the newly launched recommendation engine for Google+ users and while it is not affiliated with Google+ and is completely unofficial, it is drop dead gorgeous and super simple to use. The site offers lists of users based on interests ranging from photographers, writers, designers, to LGBT.
Most interests can be narrowed down, so photographers are separated out by inspirational photographers, wedding, commercial, etc. Clicking on a user’s profile photo will take you to their Google+ profile for more details and you can add them to your Google+ circles from there.
