A pet peeve, in writing and thinking: introducing a false antagonist to create tension in a story. This is rampant in tech writing. Apple vs. Google, Ive vs. Forestall, Rails vs. Django, Ember vs. Angular, etc. But there’s no there, there. It’s only filling space.
I would love to have Ernest Hemingway weigh in on introducing a bad guy where one isn’t needed. I suspect there would be a lot of cursing involved.
