Funnier and more impactful comments. I feel like the comment section of YouTube videos contributes 80% of the joy of watching the video. I remember seeing videos on DTube and searching them on YouTube because I'd rather watch the same video on there. On DTube, the whole experience felt more eerie because you didn't see any view count or lively comment section. I enjoy reading the comments while watching the video.
Likewise on hive posts, it's hard to come across comments that actually make me laugh or entertained.
