As 10+ year vet, I still go back for certain things. Mostly communities that have not been recreated here yet in any meaningful sense, and there are a lot of those. There are people here, yes, but the niches, the non-general topics, are lacking a true community. That will come with time, but I still can't substitute Lemmy for reddit 100% yet, much as I might want to. Unless I only want to talk technology, news, and politics all day.

But I will say Boost for Lemmy has taken the spot RIF once had on my mobile home screen. Lemmy is what I open reflexively now. I only go back to reddit when I need to see something specific, I'm not browsing there. Partially because it's very tedious to navigate old.reddit on mobile, but partially because I just don't want to spend too much time there anymore.
