      a turning point for the web. Many people concluded that the web was
      overhyped, when in fact bubbles and consequent shakeouts appear to be
      a common feature of all technological revolutions. Shakeouts
      typically mark the point at which an ascendant technology is ready to
      take its place at center stage. The pretenders are given the bum's
      rush, the real success stories show their strength, and there begins
      to be an understanding of what separates one from the other.")
