The article, Individual Knowledge in the Internet Age (EDUCAUSE Review), is not exactly what you would expect from the co-founder of Wikipedia. He expresses concern that we are underemphasizing the importance of individual knowledge. Instead, we have turned to the internet as such a readily available source of knowledge that students no longer need to memorize facts. In addition, the increasing number of assignments that revolve around students working together to create knowledge is not necessarily a good trend.
He also argues that the internet is not a good replacement for a complex, dense book.
An interesting read. Makes me want to go read War and Peace. Or maybe not... :)
