A handy snippet from the Huffington Post for teaching English 516 or 444, where there are always students who have no confidence at all in things like wikipedia and who trust without question things like print encyclopedias:
“Despite all the controversy about Wikipedia’s work model, no one can argue the potential of a project that has so effectively demonstrated the usefulness of the ‘wisdom of crowds’ concept. And that wisdom has detected a large number of mistakes in one of the most revered founts of human knowledge, the Encyclopedias Britannica. Among the wrong information collected on this page are the name at birth of Bill Clinton and the definition of the NP problems in mathematics.”
