Reading hundreds of stories here on SOL has definitely made me a better writer as I've seen the breadth of story types. For a while something was bugging me about certain stories, but I'm kinda slow and it took me quite a while to pick up on it.
Some stories have the traditional rising action where things continue to heat up until they reach the climax (of the STORY you pervs, LOL) and then end with resolution. That's more or less the classic story structure we Westerners are accustomed to.
In other stories there are problems, resolutions, new problems, complications, a resolution, wash-rinse-repeat until it just sort of ends.
Stories in the latter category can be quite entertaining--"Three Square Meals" comes to mind. Unfortunately many others leave me feeling vaguely dissatisfied even though I loved the characters and the general direction of the plot. It took me a while to realize this was because the tension didn't steadily rise, or didn't end with a genuine climax and resolution.
I've concluded that generally the stories that left me less satisfied are the ones written without a clear idea of an ending. If you don't know where you're going, how can you build that rising action toward a climax and resolution? Certainly it's not impossible, but it's a lot more difficult and I think probably takes writing discipline or the willingness to go back and ruthlessly edit to pull the pieces together. Otherwise, I think there's a tendency to keep exploring the story, meandering along until either the writer or the story runs out of steam. I've read quite a few of those here.
It's widely recognized that there are two types of writers, the plotters who outline the story before starting and the pantsers who have a general idea of what the story should be about but otherwise fly by the seat of their pants. There's no right or wrong way to write and both are equally valid, but I believe even pantsers should to start with a clear picture of what the ending will look like, even as they explore the path to get there. It still leaves plenty of room to discover the story as they write it, while giving them a compass heading to a genuine resolution so they don't wander too far off track.
