apophenia: Academia and Wikipedia states an opinion about using articles in Wikipedia as citations in research papers. The author makes a good point: an entry form Wikipedia is often only form one source, and has not been vetted. There fore, it's not appropriate as a citation. He appears to be in favor of the project (Wikipedia), but cautions on its use "I don't believe that the goal should be 'acceptance' so much as recognition of what Wikipedia is and what it is not. It will *never* be an encyclopedia, but it will contain extensive knowledge that is quite valuable for different purposes. If the fuss dies down, i'd be exceptionally worried because it would mean that we've lost the ability to discuss the quality of information." The entry also includes several useful comments.
