Skype is the incumbent. I regularly hear people talking about Skyping each other. FaceTime is going to need to connect to Skype to compete. Google+ is in a pretty similar position - I chat with people all the time via Google Chat, and if there's video, I can use the same interface with a very low barrier to entry - I already talk to people every day using it. An Apple-only video protocol, by contrast, is basically just a tech demo for most practical applications. Unless you refuse to talk to people who don't own Apple products.
