IEEE Spectrum interviews David Allen.
Why have techies embraced GTD?
It's been fascinating to see the rise of my star in the geek world. One of the reasons geeks love GTD is because it's a closed system. It tells you what to do with everything: it's really a knowledge management model. And geeks are lazy, just like me, so they're into how automated they can make the system. And geeks are early adopters. They're willing to give up whatever they're doing to find a better thing to do.
