The "Ian Knot"[0] (which, I just discovered, was invented by the author of that site) is quite possibly the coolest and fastest way to tie your shoes.

That would not work for me. I need to keep one finger on the slip knot at all times or it becomes loose, resulting in a very unsatisfying knot. This has been by far the biggest hurdle to teaching my kids to tie a decent knot in their shoelaces: they can move through the motions just fine but it's always loose. I actually start with my left index finger on the slip knot then transition to my right index finger halfway through - much more complicated than it at first seems.

The reason your knot does not come undone has nothing to do with tension and everything to do with the order of the way you tie it. Left over right, then right over left. If you learned the standard knot as a kid in the right order and continue to do it the same way today, then the Ian knot will tie the exact same knot. The only difference is that the Ian knot will wear your laces more evenly and it ties faster.

Knots I've tied Ian's way are the most taut, precisely because I have no issue applying tension all the way, instead of the old method with switching hands and stuff, where that was impossible.
If you're doing it right, the result is not like keeping a finger on the slipknot - it's better (and simpler, faster and as taut as you want).
