Hangouts are the killer app of Google+. You're right that the "emergent" part doesn't really work well. It's a really useful tool that works much better than skyping. I've had heaps friends join Google+ purely to be part of a video chat session we have to catchup. But there really is a heap of potential here. I'm part of a language-learning study Google+ group that hosts weekly chat sessions. Unfortunately for us, the room is limited to 10 people (and two spots are taken up by the moderators), so most people would miss out. I wish the group was able to create as many hangout sessions as needed, place a single moderator + native speakers into each session. Would be a seriously killer app among language-learners... Maybe I should have a look at the API or something :P
