Well, I tried  2 or 3 zero-carb experiments for a few weeks each, c.3-4(?) years into the diet. They were disastrous. At first, I would get a great feeling of enhanced concentration and energy-boosts, then, after  a period of 2-3 weeks get massive carb-cravings, after that period I would get increasing fatigue, feel extremely dehydrated(even though I kept on drinking lots of mineral-water), and my appetite would collapse so that I would have to struggle to force down a little raw animal food each day. By week 4 I'd have massive fatigue.

I vary my intake of plant-food so much, it's impossible to say how much I consume, these days. Some weeks, I'll have only 0-300g of blueberries, say, other times, I'll load up on the raw carbs(I make it a rule to go for raw carbs during certain gatherings, rather than eat cooked foods).

I actually tried adding salt during one of those experiments, in order to enhance my appetite. It didn't work.

Fair enough. But on at least 1 such experiment I made sure to avoid (carb-containing) raw liver, except in very small, fortnightly  amounts, and only ate meats/organs from land mammals(with lots of raw suet), with no carb-heavy stuff such as oysters or mussels.
Plus, the effects weren't just awkward but almost life-threatening(I had heart-palpitations etc.) At the time, 3 years of rawpalaeo(2.5 years of non-dairy rawpalaeo?). I agree that it's possible to do zero-carb properly, like Lex, with no issues, but there will always be people with unique circumstances etc. who can't handle certain foods like raw carbs or zero-carb or whatever. Craig suggested an issue with adrenal burnout - I had former adrenal-related issues, but, while they'd cleared up by then, it's always possible that my adrenals were functioning OK but not enough to sustain zero-carb - a wild guess.

I suppose it is possible that I was eating too much raw fat, as I made sure to eat vast amounts of tongue and suet/marrow to avoid the scare re rabbit-starvation. Not sure whether I want to risk doing another trial for 2 months or more - I mean, the usual limit for me is 5 weeks before I have to give up.

Ketosis is bad, keto adapted is good I'm starting to get my head around it. I think I'm in ketosis because I eat a lot of liver and fat maybe too much.  85% calories come from fat and I tend to overeat. I have also been doing a lot of cardio so I must be switching between the being keto-adapted and then wasting them. I haven't noticed any adrenal problems from that.

Yep, heart palpitations like I've never had when I started zero carb, especially when surfing. Its an explosive sport so I don't know how that effected it. I got a little freaked at one stage. Don't get them that bad anymore though.

Ok, I will have to try cutting down on my fat. Heading for Keto-nirvana.

Good questions.  I don't think zero carb is the model of the forum, however, many members do follow such a plan.  In terms of humanity, I don't think there is one raw paleo diet that fits all.  People in the tropics exploited more plants, during ice ages more animal foods, etc.

rawpaleo.com will be updated again soon, and I agree with you: I want to learn more too.
