I've written a few poems based on exactly what you've written here. Can you call it writer's block if you write a couple paragraphs about how you're struggling with writer's block? We all know about a lot of things, and although a lot is indeed trivia, that's because it has no context. Once you place it in context, everything changes. The fact that Robert Stephenson's locomotive 'The Rocket' was the first practical steam locomotive, and ran in 1831 is nothing but trivia. I've said, something existed, who created it, when, and even the name of it. Yet that all means precisely dip. But if you take that and put it in the context of a discussion about what helped trigger the Industrial revolution, or the development of transportation technology, then it becomes a very good, and very interesting tidbit to use to illustrate that turning point in technological history. Such as talking about how reliant everyone was on muscle power alone, with horses and their own legs being about the only way to get anywhere. Then James Watt and friends coming up with this really cool way to pump water out of mines that this one weird Robert Stephenson fellow thought might be good for making a self propelled locomotive machine that didn't actually need a horse, and which would revolutionize the world. And if that's not enough, then there's these two crazy bike mechanics 70 years later who think they're birds. Man, fly?? what a load of crock.
See, trivia is only trivia when it has no context. There I've mentioned all kinds of trivia, who is responsible for the steam engine, what it was used for, who built the first locomotive, and that 70 years later a couple bike mechanics were trying to make man fly. All not quite so pointless though this time
