I would say some boards on 4chan, some forums and some discord servers, and some subreddits can be good for meaningful discussion- if you have niche tastes and don't mind putting up with a handful of stupid people. For example, I enjoy painting and weightlifting as well as programming, and can list several places I enjoy going to discuss and share stuff related to those topics.
In my eyes, the issue with modern internet communities is that there are too many people there "just for the sake of it". I find that communities focused on a specific thing don't suffer from the repetitive and bland drivel that fills the front pages of most discussion websites.
Due to the nature of this advice, I won't just list a bunch of forums and discussion boards I look at and post on. I'd recommend you search for places based on your interests.
