@cliffhensley Hey, I checked your profile, and you are following no other account. You'll not have recommendation, or suggestion here, you need to use the search box, and search for hashtags. Discover peoples sharing interest, and follow them. That's a way to populate a post feed/TL. Good luck with it.
@davidrevoy Thanks for looking! I appreciate you trying to help, truly. I’ve actually followed a bunch of people, but it still says I’m following no one. If I search them out though, and open their profile, it says I’m already following them, even though according to my profile following count I’m not. Also, there are accounts showing up in the “Post” timeline on the Mastodon app, none of whom I actually follow. But even the “Post” timeline stopped updating a few days ago.
