I agree with John W.; the idea that Mr. Simmons wouldn't hire anyone without a blog is ridiculous, especially given his reasons. There are perfectly good people out there who don't write blogs because:

a) they think it's stupid to "tell the Internet" about what they're up to every N days (if not useless);

b) they don't have the time or they do but they'd rather spend it doing something else;

c) the world was perfectly fine before blogs were "invented" and, personally, I think that if you look at THE_CURRENT_UNIVERSE_OF_BLOGS, you'll find more noise than valuable information anyway. Therefore, the 'blog' alone is not any indication of intelligence, wisdom, or what have you. People lie. Especially on the Internet.
