Excellent blog post, and an explanation of 'Show, Don't Tell.' The first time, I ever heard those words, it didn't have an explanation attached, and I instantly had a dislike of the whole phrase. To the point, I stopped writing for years, before I took it back up, and avoided Editors, and Beta Readers who used it. 'Show, Don't Tell' became a curse word in my dictionary. However, I am happy to see people actively explaining it, instead of just tossing it around, as a way to infer someone is writing low-class work.
This.
As someone that writes a ton of SciFi and Fantasy, there is a lot of Telling going on. Otherwise, your reader doesn't understand the world, or its rules, your writing about.
