interesting point. I fully agree with that. Every answer is a wiki page. However I strong believe that if the question isn't specific about versions, an answer to an old version of code (gem/pip/etc version X, instead of master) still right. Example if for the question "How to print to stdout with python", the answer " print 'foo'" is right, you just have to use python2.. it is maybe staled, outdated, but not wrong.
