>You have to write, you have to tell people
Given that I'm not already famous, how do I get people to know that I wrote something?

Build a network. Some place like Mastodon ... it's a social network, so you join a server, watch the feed, see things you like, follow the people who said it, see who they follow, and follow them as well.
Then say things that you think the community will find interesting. Boost other people's posts, interact. People will start to follow you back, so make sure you say things you think your followers and your community will find interesting.
All this will build a network, and people will see what you write. They might not interact with it much, but they will see it.
Consistency and persistence is key. Start, continue, and keep going.
