title: I See a Lot of `<open></close>` Tag Sets That Contain NO Data, Doesn't This Negate the Tag?
body: <p>As I've been answering questions, I've noticed a lot of code examples that show tags like <code>&lt;span&gt;&lt;/span&gt;</code> with nothing between the tags. What's the point? If there isn't anything between the tags, wouldn't the tag be pointless? <br><br> I realize that many of them are simply examples, but there also seem to be a number of people  that think it's "okay" to writhe the code that way. Is this a "thing" now?</p>
