The actual content is way better now than it was the first couple of months after the Reddit thing. Initially a lot of the comments were either Reddit related or people trying to force communities that didn't necessarily have the population to survive, yet. That's all fallen away now and the content feels much more organic. Someone opening a Lemmy instance for the first time is going to find today's front page much more engaging than what it looked like in June/July.
Lemmy is becoming its own thing rather than a reflection of Reddit.
In some ways a lot more responsive as well. The news that Kissinger died was all over Lemmy for hours before I noticed one post about it crack the front page of Reddit, for example.
