Although I disagreed with some of his opinions, I will miss his voice in the atheist world. He was one of the few outspoken atheists not to come from academia or the sciences. His voice was the voice of the common sense human being who looks at the world's superstitions and the damage done and says "This is crap."
Of course as an atheist blogger who isn't a scientist I appreciate that voice. I also admire his way with words and I believe he opened the door for other voices to join in. With Dawkins and Hawking we have representatives of the "answers" that counter the creationist worldview. A lot of believers take the Genesis story with a grain of salt, anyway, so we need to point out the many other reasons why religion is false. Hitch took on the "Religion does good things" meme.
