Purpose
Perhaps the article was written more to spark a discussion than to exhaustively cover the possibilities? There is a lot of expertise available on this site, and it is well to tap into it....
Perhaps if we think of a given project as being analogous to building a house - at some point you need an architect, where creativity is welcome - perhaps required? - but you also have to get the bricks laid straight, and the plumbing correctly engineered. Save us all from too much creativity in these areas!
Ley us all enjoy the ENTIRE experience, or skip to other areas if your time does not allow such enjoyment.
