That may be where you went, but you've also bailed on Reddit as soon as they went bad too so you're a biased sample.
If you look at the graphs of the actual traffic visiting each of the sites, it took years for Reddit's activity to surpass Digg's and match its old level of popularity after Digg v4 rolled out. Here's an old article I just dug up with one such graph, I remember seeing a more detailed one recently but can't find the link right now.
We here on Lemmy/kbin are not "typical" users, we're early-adopters and the sorts of users who are most aware of and most sensitive to the sort of problems that Digg and now Reddit are inflicting on their userbase. The rest will follow, slowly, as the degradation grows and reaches their thresholds of awareness.
