I should say, whether you believe me or not, that I am not a "Randroid" and do not agree with many (maybe most) of her ideas. I am more interested in her as a pop culture phenomenon who appeals to geeks. She was one of the first well-known writers in America who made geeks feel good, even heroic, about themselves.
