We totally agree with you. We think that Google+ Hangout could be an useful tool for discussing about code. We're developing a realtime collaborative web code editor (http://cocode.io http://cocode.io) exactly to fit the same needs: have a place where programmers discuss about their code on the fly. They throw their code snippets on cocode.io, chat about them and typically throw them away (or, possibly, save them as gists). Moreover, we're going to optionally integrate cocode.io as a Google+ Hangout app. May be it of any interest for you?
