Very nice piece. While I might disagree with his conclusion that reduction is not as good as quitting cold turkey, I also understand that he's taking an approach relying on epidemiology, while I know that cold turkey isn't a viable option for me, and many others, from a mere personal perspective.
His approach is very wise. Essentially, he's saying what works for most, but if that doesn't work for you, don't give up. Very excellent and inspiring thoughts. Everyone should read this.
