I'm a noob. That sounds like the opening line of a "noobs anonymous" meeting. Hi, I'm john_b, and I'm a noob.
But I digress.
I've read and heard discussions for and against adding water, and I can understand both views. With only a few scotches and a couple of bourbons under my belt, thus far when I've tried adding even a drop or two of water it ruins the taste experience. I've tried a few neat, then tried them again with a touch of water, and it just doesn't work for me. To each his own.
