Once you start paying attention to misplaced modifiers and con-
fusing word order, you’ll notice it everywhere. One word you’ll see
frequently misplaced is only.
So it’s not: Only publish good content.
It’s actually: Publish only good content.
Why? Because the idea isn’t that you should only publish—and not,
say, also create and distribute—good content; the idea is that the
content you publish should be good.
In other words, only needs to modify good content, not publish. (A
handy writing hack is to think twice about placing only immediately
before a verb.)
