Pick a topic and put a hashtag on it, put it into Google+ search. Here's one - try this: #googleplus
Flowing in front of you as you scroll down you will see over a thousand people in the first 30 seconds. Like a candy store, so many people, so many faces, how do you choose?
You can create a method for this. You want everyone but don't add everyone. Use some wise judgement. What are you seeking? Who will have authoritative information. Who is already popular. These are places to start.
First you see faces. If you don't see a face, then it is a business. That's okay. But you want to communicate with people so go for people first. If you don't see a face or a logo, keep moving because it is somebody who is not interested in some real communication, not enough to show their real face. Google likes faces as it can recognize them and also post them on search results more readily.
Some faces you may know. For me, I already have many of these people in my circles. The green boxes are all people in my circles. (But, gee don't all these handsome men look terrific!) As you can see, it says their name and this is followed by what they do. It also tells you if you know people in common.
Then you pick the ones you like and go check em out. Click on their picture and you will see their page. You want to look at two pages about them at least: "About" and "Posts".
In their "About" page you can see if they posted anything. The people who have shared what they do and where they work, these will be most interesting to you. Some folks just say "male" and stop there. Blah, they don't care enough to want to meet people.
The people who will gain more followers and be scanned and shared more easily by Google on search will have a profile filled with information. The details of important points to fill in will be shared in another post. For now, just check em out and be sure there is something there to check out, or move right along.
