That is one of the best actionable pieces of advice I have ever seen him give, because the vast majority of his work, and well thought blog posts on nontechnical topics, is evergreen: it continues to be worthwhile years after publication. The preference for the new because it is new is irrational, and the constant content treadmill aping newspapers (who need it because they have a new paper to put out every day to wrap ads around) is a terrible idea for most bloggers. Ditto for those of us who do publishing for our businesses.
