Google+ and the Hangout feature

When Google+ came out I got quite excited and thought that I might use it instead of Facebook. In particular I thought the Hangout feature might be a really good way of communicating with students - even a group of them at once. Well, I have only a few friends on Google+ and have largely forgotten about it and them..... As for Hangout it's too late now as my students are mostly doing exams. I've missed the boat. Phil Bradley has done several posts here  and here  on Google+ Hangout so that has reminded me of my failure. I wonder if anyone out there has used it for Information Literacy in any way?
