The idea is important but the execution is flawed and a bit delayed: A Seismic Shift in Epistemology "The epistemology that leads to validity of knowledge in Web 2.0 media such as Wikipedia is peer-review from people seen, by the community of contributors, as having unbiased perspectives."
I have rather significant issues with how epistemology, consensus, and knowledge are treated in this article. I'm not fully convinced knowledge is collectively created. By my definition, most of what the author treats as knowledge is more like information. And if the discussion is primarily about information, epistemology as used does not apply either. So, I'm conflicted. I like the distinction the author tries to make, but due to fundamental disagreements in how information, knowledge, and epistemology are treated, the article is more of an entrance into the conversation than one that can be used to shape the larger discourse. As is often the case, we can find a better more complete effort addressing the subject in the edublog space, in this case, Stephen Downes' Connective Knowledge article.
