One thing I've noticed as I get more and more into my vegan diet (which I am still on) is that there isn't as that much information about it as you might imagine. Since the fairly "strict" veganism that I'm tracking right now discounts the value of supplements (some are useful like Omega 3 and B12) and since it's rather simple to do ("eat your veggies"), there isn't a "business model" for the dissemination of information about veganism - at least to the extent that there is for sophisticated and difficult "get thin quick" diets, "exercise in the comfort of your living room" devices, supplement businesses and campaigns driven by the huge advertising budgets of the snacks, meats and dairy industries.
I have a feeling people did more things in an amateur (for the love of it) way in the '60s. Having said that, this whole "social software" space is supposed to be about "amateur content" and it seems like ideas like veganism should have a larger footprint on things like wikis.
Anyway, I went to take a look and noticed that there is in fact a vegan.wikia.com. I've started adding a few things and am sorting out structure stuff with the existing "residents" but if you have any tips, recipes, favorite restaurants, theories, books, resources or other vegan things to share, please sign up and contribute. I have a feeling this is a perfect Wikia application.
