With various instances it can be hard to find new people on here, even if you hunt, so I think #followfriday really works here, better than it did on the bird site. @FediFollows sometimes suggests them

Don't worry about missing people out. It's not about naming everyone. Just a couple a week #ff
Here are some I like to follow (there are _a lot_ more, but I don't want to overwhelm people😅).
They are all posting about software engineering related topics, but of course also about other topics (sorry for the generalization - in this case it helps, though):
The Wandering Shop is a Mastodon instance initially geared for the science fiction and fantasy community but open to anyone. We want our 'local' timeline to have the feel of a coffee shop at a good convention: tables full of friendly conversation on a wide variety of topics. We welcome everyone who wants to participate, so long as you're willing to abide by our Code of Conduct.
