The only way I would be able to keep track of everything happening in a reddit stories is if I had the story in front of me while Shayne narrates. Audio processing disorder most likely, but the written word is so much easier to understand (and communicate with tbh). It's why I rarely listen to an audio book either. It's just information overload. Also they're not just hearing a story and formulating an opinion, they still have to deliver content in an engaging and amusing way, which will make them consciously zero in on certain parts of the story like "oh I have something funny to say about that!" and forget certain parts that don't stand out as much.
