Daily I see posts and articles on how Google+ is the new Twitter for educators. I am no where near ready to leave my Twitter PLN (although most of the educators I follow are already in my Google+ circles), I am using my Google+ communities to learn daily. As we make the transition to devices that are more friendly to Google Apps in Education, I believe that we can learn and grow if we use Google+ Communities. The link below is a good article on how to get started with Google Communities.
I would also suggest once you begin to explore Google Communities, that you check out these:
