Web 2.0 Wikipedia and the Encyclopaedia Britannica

The web has evolved from web 1.0 to the current web 2.0. The former refers to the fact that information was added to the web in a much more controlled manner by a few expert people. Web 2.0 on the other hand uses a much more "collective intelligence" with lots more people contributing - Wikipedia for instance.The scientific magazine, Nature, undertook a study to evaluate the accuracy of the Encyclopaedia Britannica to that of Wikipedia. The results showed that the traditional encyclopaedia did indeed have fewer errors - but only slightly less than Wikipedia. The 42 experts who contributed to the study discovered that Wikipedia had 4 serious errors on the data researched, but interestingly Britannica did as well!
