I already saw this happening on Reddit. The largest subreddit were filled with generic posts. They got a lot of content, not necessarily good content. But there were plenty of small or medium sized subreddits that had much better content. The Fediverse feels like it is missing the big subreddits. It also feels too small to have the small niche subreddits. What is here in terms of content feels more like a few medium sized subreddits.
