I did the same. I have some exceptions for technical topics on Reddit. I also still use Facebook in a very drilled down state (looking into it every 3-5 months and checking in with some remote friends). I have also set up my own Mastodon server, which is fine for niche topics and I can reach out to interesting people directly, where other channels fail (email). I heavily rely on RSS, particularly from people that I trust or who gained my trust over longer periods.
