Good info. A very basic start type of info that it would seem everyone should know and build on for there individual needs.
Here in North America I kind of feel the info was produced, made available, but with an attitude "it is there if anyone wants to use it, we have fulfilled the minimum obligation to our department" I think it should be promoted more, better, and deeper into communities. For instance Sweden teaches it in the schools, and I suspect community classes and other outlets. Not entirely sure of the depth of there network.
