I'm another user who left during this and came to Lemmy. As a non-tech person, though, it really wasn't the easiest migration, and I do think you can see through Lemmy's content sometimes (love for Linux, well-upvoted IT memes, programming humor, etc.) that it is a different crowd that was able to make the migration in general.

My city's subreddit is incredibly active, very human, and still gets a ton of traffic. I usually check it once a week just to keep up with what's happening locally, but I don't log in and just scan the feed titles. That type of valuable local platform is unlikely to ever exist on Lemmy, which is sad.
