On 15 January 2001, two Americans - Jimmy Wales and Larry Sanger - launched an online encyclopedia. Wikipedia. Despite much criticism early on about inaccuracies, it has gone on to be hugely successful. It is the 15th most popular destination on the web, is available in more than 300 languages and is maintained by a community of volunteer editors. Today, I think we all should honor the immense resource Wikipedia actually is, hoorah!
