How to share posts publicly on Google+
To do this, ignore all of your circles, or groups, or whatever, and just select *public* when you post in Google+. If you haven't done that yet, go ahead, and it will be the default the next time you post. Remember that Google+ is not Facebook, it's not just for talking to friends, it's for communicating to the world.
Google+ is a place for exposure, and for shouting out good things to the world. If you do it correctly, it indexes in Google, the biggest search engine there is.
Now, go share!
