I guess it is pretty well known by now (at least two of my friends knew it already), but somehow managed to skip my attention till today. I came across a web site called wikiHow today. The Welcome box on its homepage says that "wikiHow is a collaborative writing project to build the world's largest how-to manual. With your contributions, we can create a free resource that helps people by offering clear, concise solutions to the problems of everyday life. wikiHow currently contains 9,821 articles written, edited, and maintained primarily by volunteers. Please join us by writing a new page, or editing a page that someone else has started. " (italics are mine)
I loved the first How-To I read on it- How to Eat With Chopsticks.
