>So would be much more useful if there were some effective mechanism to get rid of or correct entries that were answered incorrectly in the first place or have become incorrect or no longer relevant with time. Sometimes, the community will "fix" that by having a newer answer get upvoted beyond the "accepted" answer. E.g. a Python 3.2 answer with more modern syntax in 2014 gets upvoted above the Python 3.1 accepted answer in 2010: - https://stackoverflow.com/questions/2331592/why-does-datetime-datetime-utcnow-not-contain-timezone-information/24666683 https://stackoverflow.com/questions/2331592/why-does-datetim... But that type of "correction" only happens on popular questions. The more obscure questions and answers that are wrong will remain wrong because there are not enough eyeballs and/or widespread expertise to fix them.
