Oct 28, 2009 at 7:45	comment	added	Andrew Stacey		I don't like your summary of Rezk's answer to that question. It's an oversimplification to say that it "comes from the wedge product". It comes from the wedge product together with the properties of that with regard to connectivity together with the fact that the first homology and homotopy groups agree (modulo a little abelianisation). So I think best just to redirect to that question.
