Exactly. The users who have moved here are disproportionately commenters, power posters, and moderators from reddit. I was a top 1% poster on reddit, lots of OC, but I've essentially stopped participating there. I occasionally comment, but I don't make posts on reddit anymore. If a significant fraction of power posters (and not just the reposters) and moderators migrate to lemmy, lemmy will have disproportionately good content, while the reddit experience will degrade further into reposts and poor moderation. I think lemmy already has disproportionately good posts and engagement, just still pretty small at the moment.
