Don't limit yourself to reading posts from only the people who speak your native language. An extension for your Google's Chrome Browser translates any post in just about any language.
Each Google+ item has three buttons at the bottom; +1, Comment and Share. Google Translate for Google+ puts another button next to them; Translate. When someone posts an item in a language that is foreign to you, just click on that button and it will be translated, inline for you to read in your native language.
