Whizle.com is a very interesting site. It will allow you to start your own guide (or Whizzle) and gradually build on it. This will let you show the world how to work something, by allowing them to see how you learnt it yourself. For instance: if you just got an iPhone, start a Whizzle and add to it every time you learn something new. This will allow you to keep a sort of blog on anything that might require a guide. In turn, your blog will become a guide to someone who needs help or guidance. The variety of topics is amazing. On the site, you’ll find guides and tutorials for just about any type of activity. You can build on what others have written, making this a communal knowledge experience, much like Wikipedia. It’ll be very interesting to see this grow and add more knowledge to its database.
