On top pf being the spcial media I interacted the most, Reddit also used to be my default idle scrolling app, whenever I had time to kill and a phone with Internet on my hand or when I felt like multitasking watching TV. I stopped using it for the blackout and I never really went back.
I snooped a bit through r/modcoord and r/save3rpartyapps to see how thing were going when someone mentioned them a couple of days ago and from there I went on the linked subs to see their alternative protests and vote on the subs I subscribe to, but that's it.
I still miss some subs, but I haven't felt the need to visit them yet, so even if I cave in, I'm no longer a daily user, just a once-twice a month one with a ton of ad blocks.
