Not the parent but every time this question gets asked here it usually gets a few responses along the lines of "the more specific the topic the better the content/community generally is" and I'd agree. A few I enjoy are r/homelab, r/programming, r/Economics, r/networking, r/AskHistorians, and r/ColorizedHistory.
