I used to use dev.to a lot, they definitely do great community building, at least as of a couple of years ago. Aren't they more aimed towards beginners?
Yeah. They have some settings to set what type of articles/posts you see, but it's very beginner web-dev centric. I stopped going there awhile ago because I wasn't finding anything there for me. IMO it's a very, very good replacement for Medium as a blogging/long-form writing platform, but content discoverability is lacking.
