Honestly, I haven't missed it. I'm no longer doom-scrolling an eternal screen of karma-farming bullshit.
I took part in the blackout protest and tried Lemmy at the same time. When Reddit proved they didn't give a shit, I went back long enough to scrub my post and comment history, before deleting my ~15yo account entirely. Sure, they could probably recover the data, but why would they?
I use Pihole for DNS and a private searx-ng instance for web search, so I just block all Reddit domains in DNS and search results, and it's genuinely like it doesn't exist for me any more.
Also, the pace on Lemmy is much nicer, IMHO. I find a lot of days I only look at Lemmy a couple of times, and very quickly move on if there's no posts of interest to me.
