If you haven't been living under a rock in recent times, you would be fully aware of the serious financial crisis in which the US finds itself. And as the contagion spreads, in smaller measure, to the rest of the world, people's thoughts often devolve to cost-cutting.

A primary lesson that this genre of software has taught people is that openness is preferable to secrecy.
