Hey from Reddit! Your stories do show up in the tags' pages. There is a "Latest Stories" section at the bottom of each topic page. Click on the Visibility tag at the bottom of your story to see what I mean.

I'd suggest looking at joining some publications and pushing your stories through them. They provide an existing audience and it's basically a requirement for new writers to more easily find readers.

Smaller pubs tend to provide better engagement than large ones with thousands of followers.

When I started writing here, I thought pubs were for fairly established writers but that's far from the case! All pubs have a story about how to join. Which can range from simply commenting and following the pub to fairly strict requirements. Most pubs are the former and easy to join.
