Are we really all Keynesians now?

The Economist is in the process of running a three-day online debate entitled "This house believes that we are all Keynesians now". The debate will run all this week at Economist Debates. At the moment, the general consensus is that no, we are not all Keynesians. What seems to be lacking so far is any acknowledgement that maybe we need to look beyond the neo-classical/Keynesian labels.
