It's an excellent site It's and excellent site with a lot of practical well researched and thought out low tech solutions to the sort of needs that are likely to be experienced in a post industrial society.
Having lived with third world types for a couple of years that is dubious. Here, being literate or not is a choice, there it is a way of life. Returning to the topic. There is a sort of a relatively unknown insider's magazine called the Resister. It is the underground voice of the US Special Forces. Some of it is of interest for survivalists and preppers. It contains ~4gb of articles unlike most survival information more military based subjects are included. Self-Reliance Main Topics: Self Reliance Some of the links have been suspended, however there are also ones such as "GUERRILLA WARFARE TACTICS IN URBAN ENVIRONMENTS" which still work. Disclaimer: reading a book or manual on such things only makes you well read.
Cultural bias? hmmmm methinks your biases are showing a tad......or you have been watching too many discovery channel docos where the natives are all dancing around a missionary filled stewpot whilst wearing lap laps, or grass skirts...and with bones poking through their noses (the natives...not the missionaries). Just as not every 3rd world person is dirt poor....not every 1st World person is fabulously wealthy, literate and numerate.
Even though folks MAY be literate, and have a computer, that does not necessarily mean that they have a connection to the internet, to get at the 13 GB of Data that the OP was showing, or the bandwidth to suck it down the connection to be used locally. Way to many "IFs" to make such blanket statements..... YMMV....
Yes, that's why the CD/DVD is available for free to 3rd world addresses, and $20 for folks like us, which is still a great price. Downloading it is only a perk, really.
As I respected them and still do there was no bias. Besides they had skills most literate people lack. Even in High Def Discovery doesn't do the experience justice.
