Students from various schools and colleges often tell me that their tutors have informed them that Wikipedia is an unreliable source of information which should not be referred to – and this seems to be common (see, for example, Jaschik, 2007). This is clearly the opposite of Web 2.0 thinking – it is ‘Do fear the internet!’. However the notion that any statement that anybody has ever managed to get into a book or article is going to be inherently better than Wikipedia content clearly doesn’t make sense, especially as Wikipedia is subject to continuous checking and updating – precisely unlike anything in print.
