I think video chat isn't done exactly right , so it hasn't become very popular. You see this in many responses to google+'s group video chat. many say it's done right and want to use it. Another hint is group telepresence for businesses. it's pretty successful even tought very expensive. And some people who use video chat to remote relationships use it in a unique way: not the center of the experience but part of a shared experience. So they put a video chat on a laptop and in their main computer they watch a synchronized movie together , for example.
