That article was an oddity, actually. If we had to do it over again, it would have been a normal article.
Besides the normal front page articles -- which is the bulk of what we publish -- we sometimes publish comment-less articles that are meant for reference or social media. Prime example would be a very basic How-To that we don't feel is "front page worthy" but is nice to have as a reference for people searching or for us to refer back to. Sometimes we also have other articles which highlight older topics in different ways, for social media.
As I said this one is an oddity.
