For example, have you ever tried to schedule a Google Hangout chat? As far as I can tell, there's no way to do it from Google Hangouts. You need to first sign in to Google+, then go to Google Events and create a new event, and then you have to specify that it's a video event.
Is it a use case they just don't care about? Is there no one at the company who's looking at this setup and thinking, "wow, this is confusing and we can probably simplify that"? Or is my brain just getting too brittle to make sense of it?
