I was very happy to read this post on WP Beginner in support of leaving dates on blog posts. It’s bugged me for years that WP Beginner (and loads of other sites) didn’t have them, because like they say in the article, it makes it hard to verify the usefulness of the post if you don’t know how old it is. WP Beginner gives a great argument for including dates, and proposes a nice alternative to show last updated dates instead.
