I can’t speak for others, but I literally never looked at r/all. I went directly to specific subs, mostly small and/or specialized. I had been on the site for something like ten years, and while I wasn’t online every day, when I was online, I was talking to people rather than lurking. For me, the whole reason I had to leave is that I went there to engage, and now that the company has made the “business decision “ to become a shithole, I no longer want to engage. So I have taken my 100% of my engagement here. I wouldn’t be surprised if there’s a link between being an active participant and feeling upset enough to leave. If I had been a lurker, it wouldn’t have mattered as much to me that I no longer feel comfortable contributing to spez’s data hoard.
[edit: also, as someone who was there as much to connect with cool people as I was to talk about particular topics, I am not missing specific subs nearly as much as I expected. I am getting more or less the same emotional payoff here as I did from Reddit at its best.]
