When you're starting out with a totally empty timeline, the directories are probably best:

https://fedi.directory
https://communitywiki.org/trunk
https://fediverse.info/explore/people

Once you've got some people in your timeline, you'll see posts shared and people mentioned in discussions.

There's the Explore tab (on the website) or the magnifying glass 🔍 icon on the official app.

Also, when it's relesed, following hashtags will help a lot.
