First of all, I must confess that I like to read (and, occasionally, to write) survey papers: They mark a pause in the hectic racing for publishing papers, and allow us to take stock on questions in a given area. I would even say that, when looking at the way my colleagues (the youngest ones, but also some others not so young): “Everybody writes, nobody reads…”
