I'd be astonished to read news from him, let alone an entire interview. This guy is worthy of respect not only due to his extreme devotion, envisioning and success to a fundamental problem in economics, but for him being a badass Internet mystery. I mean think about it. Someone, in some unknown corner of the Internet, devoted time and energy to connect the dots and create easy to spread but hard to stifle, as he called, networking solutions for very existent problems, shared the source code for everyone to check, ensure to have loyal people in charge, and then disappear.
