Since I often just post a link in order to indicate that a post is a dupe, I should have been clearer here! Reposts are fine after about a year [1], so you were quite ok to post this. I mentioned the link from 4 years ago only in case people would also enjoy that discussion.
Please don't stop posting substantive, out-of-the way articles. We need more of those and the occasional duplicate isn't a problem anyhow.
