This question already has an answer here:
I have come across many questions from 2+ years ago that have answers with outdated info. For example, this question from June 2011 uses the jQuery
.live() method, which was deprecated in jQuery 1.7 (November 2011).
Should the date be emphasized after two years, or a banner shown above the question? Something like "Note: this question was asked and answered over
n years ago."
