Ok here is one guy from the world of information tech whose books and articles I read a lot. He seems to be really competent and knowing (even if slightly arrogant to the point of being "all knowing", lol). The way he writes is quite natural for me to read and I can't make myself to disagree with him in pretty much anything. I wonder if you can type him based on these pics. These are all posed pics but that is all I could find...
