No I definitely will give him that point. I completely agree that showing the relationships between certain knots and others is a great idea and definitely helps in learning more and more knots. But I think the idea of trying to rename knots is a bit off kilter. You're dealing with the fact that these names have been around for how many years? Over 100 or more for most of them right? So you're fighting a lot of tradition there. Robin looks old enough to know how well that works...
I like the idea of showing similarities between knots and think it would be a great way of teaching other knots. I think this would go really well if you started with the basic knots, and then built up around that. Showing how "b, c, d, and e" knots are really nothing more than "a" knot modified or repeated or interconnected, etc. This of course would also tie into how knots are classified, indexed, whatever. So in that respect, I do applaud Robin in his efforts.
