> publishing my french articles to a selected group of french people, hiding the content to anyone that might be interested and I don't know of
On google+, it's the publisher who decides which people are in which circle, not the reader who decides in which circle he wants to be (and circle names and person list are totally private).
So, if you publish to a circle rather than publicly, only people you added in circle will see your content. It's not guaranteed they actually care about it, and those who care about it and you don't know won't be able to see the content.
As others have mentioned, circles are meant for privacy (I want to publish this to my family, that to my close friends), not to separate content (I want to publicly talk about politics, I want to publicly talk about cats).
