In YouTube, you’ll mostly just see Reddit stories being presented with some minecraft parkour in the background. Somewhat most of them are automatically generated by a software that picks a ongoing or hot post in the selected subreddit, gets some top comments and then a TTS program reads the comments out. It is possible to make this for Lemmy as well. Though it depends on how “true story” the Lemmy users can make. I can already see c/asklemmy being one great candidate.
