People are talking on twitter or facebook, new ideas are forming, spreading, growing, diverging and converging. Along with good inspiring ideas, practitioners join together to do certain practices, and then form social circles and knowledge domains. When a newcomer joins the formed community, they need a leading guide for their new journey, and the practitioners condense their ideas into a "scaffold" for the newcomers to climb. Several "scaffolds" had existed for several thousands of years and even more, they might be well-formed already; but in general, the "scaffolds" are alive, and are leading us on the road of our everyday life.
