I remember at one point reading an interesting exchange between GI3 and AG where among other niceties, the former was banning the latter from using the DIR term in association with any training he was to impart. Since there was no trademarking of the acronym, we all know that did not happen. I agree with John when he asks that the UTD side of the story be also included. It will provide a more universal picture. Otherwise, instead of calling this article DIR, it would be more accurate to call it just the GUE article.
I think it would be good to show the different direction (for good or bad) that UTD is taking. I think mentions of the Z-Diving, MX-90, MX-Z, an other developments should be presented and then lead to the readers asking themselves "is this still DIR?" or "what is the future of DIR?", and "is it still the best way for me to dive?". I think that kind of introspective internal debates should be a core element of a truly "thinking diver".
I don't think anything good will come from taking the attitude the defenders-of-the-faith that are looking to incarcerate the heretics that go against the heliocentric approach.
Additionally, I also think more space should be given to the influence that DIR has had in the rest of the scuba world. Dan indirectly mentioned something along these lines when he said that other agencies are not as bad as they used to be. How come now we see that the long hose is nearly universally acceptable. Now even PADI has their own version of Fundies:

I'll say it one more time, I have no GUE or UTD training. However, as my diving evolved and I did some research on how to do certain things, time and time again I found myself deciding that the most logical way to do these was the way DIR was proposing. When I decided I needed to be using doubles, rigging stages, or choosing a harness, they presented the most logical options.
By no means am I claiming I'm a DIR diver. I'm way too heretical to do it. But I can distinctly say their ideas have deeply influenced the way I dive and I think I'm a better diver because of that influence. Just like I have been influenced, I also think the entire diving world has been influenced. I think it would be good to note and chart this influence in the Wikipedia article.
