Also, I wouldn't sell "grumbling on this website" short. If you read or hear someone calling Allah Akbar the "Muslim call to murder" in a few months, you will know that was me at work, in the background. Or if you read "Heil Hitler equals Allahu Akbar," or "Mein Kampf = Mein Koran," you will also know where that came from. Don't discount the power of nugget-sized ideas to move a debate.
But if nugget-sized ideas aren't for you, read EF&D, or when it comes out, Domestic Enemies.
If you are seriously writing a book that is great, but unfortunately, not enough people are reading much these days, and we have to use guerilla marketing techniques to reach the media-drenched masses
