Sarge -
Jardine does not advocate extremism in light packing. In fact he says to not waste your efforts on cutting down toothbrushes, removing labels, and such (I sometimes remove the "do not remove" labels, though, since they always seem to get in the way - like one on a sleeping bag I had that was in the hood where it flapped in your face all night). I have known Jardine casually for a number of years (not well, and I never climbed with him, though crossing paths with him in Yosemite during the period he was inventing the Friend). I last crossed paths with him in Antarctica last Dec-Jan.
Jardine's original discussions of lightpacking date back to the 1950s (his Sierra backpacking book and earlier articles in Summit magazine) that I am familiar with and derived from Walt Wheelock's and David Brower's books from the 1940s and early 1950s (Going light with backpack and burro). The Wikipedia article on Jordan says he coined the term "super-ultralight backpacking", and also refers to Jardine's "Beyond Backpacking" as "important, but more biased". Hmmmm, well, I am not sure about the "more biased" part, since pursuing the Jordan writings and website a bit, I think Jordan is rather more extreme than Jardine in a number of ways. But I haven't read enough yet to decide. However, it is clear that Jordan is well after Jardine. Wheelock and others (the dates in the Wikipedia article and copyright on Jordan's book are late 1990s and early 2000s). Even Colin Fletcher's weighty tome, The Compleat Walker, has a lot on lightpacking.
As to your comment about the backpackinglight website being a memorial to Jordan, since he is very much alive (and currently recovering from a serious ankle injury of last year), it could hardly be a memorial - that's for the deceased.
You said "From what I gather, he pioneered the ultralight (20 lb) backpacking phylosophy." Hardly. As I have mentioned several times on this site, I have a copy of the brochure that Dick Kelty included with all his packs (mine is from about 1960, when I bought my first Kelty from Dick from his garage in Glendale). His packing list, including the pack itself is 15 pounds, and that is without the modern lightweight tents and fabrics for clothing. The gear is more than adequate for even a week-long trip in the Sierra in the summer. You do have to add food (Kelty's estimate was 2 pounds/day/person in those pre-freezedry days) and fuel (campfires were acceptable at the time, but he recommended backpacking stoves, like the Svea 123 which was the standard of the time).
Jim S, who appears occasionally on this site, and I go on backpacks from time to time where we often throw in little luxuries, and still end up under 20-25 pounds including food and containers of "California grape juice" of the finest quality. I should say "used to go", since Jim has moved up to Bend OR, so we haven't gotten together in a couple of years. I think Tom D used to go with Jim on similar backpacks. Then again, Jim and I also used to go on "primitive" backpacks, where we used 19th century technology. You don't have to have the "latest greatest" to be quite comfortable.
By the way, on Jordan's site, there are some interesting comments about the Jetboil http://www.ryanjordan.com/weblog/2005/11/backpacking_sto_1.html that match my experiences with it.
Last comment on the history of light/ultralight - it is always amusing to see the continual "discoveries" of lightweight backpacking, most of which just repeat what was known years ago and is quietly practiced by dozens, if not hundreds of long-time backpackers. Ya learn by getting out and doing, and by having good mentors from whom you can learn by example. I am grateful to the many excellent mentors I have had over the years.
Enough for now, since I have to finish packing and head for the Sierra for some climbing.
