Here on Mi Yodeya, we are careful to remind people that they should not rely on this or any website for practical halachic decisions. Nonetheless, it is almost certain that some people take what they read on Mi Yodeya as the final word on halacha. What kind of responsibility do people who answer questions here bear for the halachic mistakes of people who read their answers? Does it matter whether the answer was wrong or the reader simply misapplied the principles outlined in the answer?
I read in a biography of the Chafetz Chayim that he refused to take a position as the local halachic authority because he would be responsible for the transgressions of the people in town. Might the same issue apply here if people are using Mi Yodeya as a halachic authority?
