Me too - I've used Ian's Secure Shoelace Knot for the last ten years or so, and never since have my shoelaces ever come undone, nor have they ever been difficult to untie. It's a small thing, but it will benefit me in a minor way for the rest of my life.

Totally agreed, I learned Ian's secure knot 10 or so years ago, and not only do my shoes never come undone, but I've also taught a whole pile of people it as well!
