Wikipedia’s peer production model is not immune to “rich get richer” mechanisms.

Wikipedia is not a dictionary, manual, directory, or a variety of other reference genres.

Encyclopedia have always struggled with the limitations of synthesizing knowledge into paper documents because when the knowledge changes, so must the paper. Wikipedia was not the first encyclopedia to use the online medium to rapidly and inexpensively revise content in response to changes, but its unique “anyone can edit” model had the effect of entangling current events with the viability of the project.
