I relate to this a lot. I was on Reddit for over a decade, too, when I left after the third-party apps shut down. I loved a lot of the discussion over there (once I got away from some of the big subs and found smaller ones), and still kind of miss it. There really was a period of sadness when I left. I’m trying to be active over here to help these communities grow, but it’s hard to get back into it and be motivated sometimes.
