The author of a recent AP article likens the shape of the island the article references to that of a “spark plug”.
Now, I happen to know what shape a spark plug is (as I’ve changed a few in my day) but I’m pretty sure Jon wouldn’t (and I’m guessing he wouldn’t know they need to be changed or, God forbid (I can see him trembling to think of such a thing), has actually ever changed one himself. :)
I think this is something we need to consider when we use comparisons or analogies in our responses. To work, the basis of comparison used has to be something to which we’re confident the majority of the readers/reviewers can easily relate.
