I read this article too. He has some good points there. However, I don't think everyone should be buying a Really Right Stuff tripod legs and ball head. Don't get me wrong, Really Right Stuff sure makes some good products, but I also believe that other brands can also offer good tripods/ball heads for less than what Really Right Stuffs charges. Oben (B&H own brand) seems to offer good products for less. The CT-2491 carbon fibre legs and the BC-166 should be fine for many of us in my opinion.
What I am trying to say is that one should buy the best one can afford. One of my friends like to say that when it comes to tools, it's better to cry once, and smile many times. But one should not necessarily buy the most expensive tripod legs and ball head to get excellent support for their gear.
