Recently Sam Harris, author of The End of Faith and Letter to a Christian Nation, spoke at Beyond Belief 2006. Based on the way he presents himself, I believe he has a chance at actually getting the his message heard by a much larger audience than atheists have been able to draw previously. After reading Letter to a Christian Nation, I find his arguments very well thought out and easy to understand.
