I mostly just see older posts boosted into my timeline. Sometimes I browse hashtags, but being on a single user instance, this typically requires third party tools, or going to mastodon.social to be useful.

Someone comes to my attention either by following me or boosting/liking something of mine, or maybe I just see one of their posts and I’m curious. Then I look at their profile, and if I see something interesting I may boost it. Especially if it’s a pinned post, or if they don’t post that often so scrolling a short way goes back a long time, it might be something from a while ago.
@josemurilo Ah, I have to get into habit of using them again.
I stopped for a while when it was discovered that on Mastodon, when an account moves, they're removed from any lists you added them to. (That should be fixed now.)
