[math-fun] Teachers (Union?) vs Wikipedia

Over the years, I have had several grammarschoolers and middleschoolers tell me their teachers discouraged or even forbade the use of Wikipedia because it's "unreliable--anyone can edit it". One of them said all .coms were questionable--stick to .govs ! This is enormous hypocrisy--I'll bet those teachers use Wikipedia several times an evening. Do they feel threatened? I just suggested that the latest such acquaintance ask his teacher for specific examples of Wikipedia bogosity. --rwg
