Checkov’s gun is a concept that in any story, there should be no irrelevant elements as they create an expectation that’s never met. Elements, like a gun, with no connection to the story should be edited out. Assuming a blog post is a story, you cut it down until it’s all down to the essence.
I find this theory fascinating and probably right, no matter if I agree with it or not. And while I’m trying to match it when writing, I think I enjoy seeing well-placed exceptions. One of my favorite book quotes is completely disconnected from the storyline, yet it stuck in my brain and made a footprint there.
“Trout, incidentally, had written a book about a money tree. It had twenty-dollar bills for leaves. Its flowers were government bonds. Its fruit was diamonds. It attracted human beings who killed each other around the roots and made very good fertilizer.”
― Kurt Vonnegut, Slaughterhouse-Five
