Zürich based howtopedia provides an excellent collaborative Internet platform for practical knowledge and simple technologies which can be of use in all areas of daily life. Read articles about stuff like how to build a no-dig garden, about basic beakeeping principles, about how to set up a publication or how to build a biomass roof.
Through the collection and propagation of simple, practical knowledge the library encourages bottom-up, low cost self help on a local basis. I think it is a great initiative since it uses the strength of the interweb 2.0 in a smooth way to create this information hub as a point of departure for empowerment and local self-organization. And since we got the our own playground right now, we’ll fall back on this for sure.
You can of course start an article yourself.
