I find Discord is a lot better than social media for making connections. As another user said, it started out for me as a topic based platform. I get engaged in communities that are about my interests, and start posting and talking there. From being actively engaged in discussions about a common topic, you gradually start to know who you get along with, who you have other stuff in common with, and now I have several pretty good friends that I have ongoing DM convos with about off topic stuff and our personal lives.
Social media in general I think can be great if you're trying to create or foster community or a brand (as an artist, merchant, professional, etc) but for making one on one connections so far Discord is much better for me for creating actual friendships.
