Opensource projects doubling every 14 months (or so)

I would have thought that the opensource movement was maturing and slowing down. I was wrong about the slowing down bit:

• The Total Growth of Open Source – Deshpande & Riehle
  Studied 5000 OS projects and shows that open source is expanding into new domains and applications at an exponential rate: doubling time of 14-16 month (a new variation on Moore’s Law?). This paper does not consider the implications and consequences of this continuing growth – hopefully a followup will.

• Dirk Riehle – Software Research and the Industry
  Blog about everything computer science, applied and more. Much research into opensource
