That's right Hailley. This would mean we don't need profiles on all of the platforms but can still communicate with our friends on other platforms. The idea came to me when thinking about Enterprise Social Platforms. I see lots of organisations implementing them internally and see communications moving from email to enterprise social. Of course, however, these messages can only be shared on that particular platform. So, it seems that if so many organisations are implementing enterprise social, a logical next step will be communications between them.
