Showing vs Telling is a tricky business. While it sounds good, it's often a very narrow blade you walk. It works best in short stories, where the showing carries most of the story and there isn't as much plot to convey. But as Ernest points out, there are other considerations, pacing being prime among them. Also, dialog doesn't come naturally to many writers. I happen to be good at it, and use it a lot, but there are plenty of decent writers who just don't do it very well. It's not a skill that gets better with practice. Either your dialogues sound natural, or they don't.
Both Aubie and I have wrestled with 'showing more', even though we both do fairly well in storytelling. I've strengthened my showing by working at it, but again, that doesn't always translate into greater downloads. What's more, concerning typos, as disconcerting as they are, they're only noticeable when the story lags. With fast paced chapters, editors, authors and readers rarely find typos, whereas they'll find plenty in slower pieces. I seriously doubt that people's writing gets that much better when they get excited about a story, instead, they get carried along just as the reader does.
All that said, I'm not as belligerent about showing as Aubie is. But, I do like to see results, and there are better areas to invest your time than working in areas you just aren't as good at, and where improvements aren't as readily noticed.
What's more, much of the 'show vs. tell' is style. People in bygone eras prefer one style, whereas people raised with newer styles prefer the other. It's not that stories in bygone eras were BAD, it's just that they don't follow the same style guidelines (like writing in present tense), as more modern writing.
Note: To clarify, my work to improve my showing has been noticed. My efforts to improve my writing, the flow of my narrative, and remove minor typos doesn't really bear out in improved scores.
