Ziggy wrote about an unusually clued article at CNET, Three kinds of free. It is about the different kinds of open source licenses (GPL and other more inclusive licenses).
Most importantly, open source is not just about code; it is about community. You don't make a project open source just with a license. It takes the costly and time-consuming birthing of a community of code, a trusted gatekeeper function and a series of symbiotic commercial enterprises to make true open source.
That's one of the mantras of the Apache Software Foundation, it's nice to see it in something as mainstream as CNET too.
Adam noticed other things, so be sure to read what he wrote too.
