I didn't read the text yet, but I already don't like a few things about this.
You can hear the notes go flat when you "pluck" the string. So which pitch are you supposed to tune to? Granted, unless you have been in the middle of an ultra picky recording session, this probably isn't a big deal. However, that's sort of what I do just about every day.
Maybe for beginners and intermediate guitar players, this is an okay article.
