Any plans to support Google+ in this?

I don't have any plans for that no, but since I much of what I do is not planned that doesn't mean much
I've recently done some work with the YouTube api, which is probably similar so I may do something there.

Just to be clear, the point of ShareSocial is to allow addons to share to other addons and provide things like feeds that other addons can use. It doesn't contain any Facebook or Flickr code, it merely sits in the middle providing an interface the Facebook-Media and flickr addons can use. Of course as it so happens, I am the author of those addons as well
