What defines the interaction style of a nested comment system in social media?

The interaction style of a nested comment system is characterized by the ability for each comment to have direct responses to other comments. This structure allows for a threaded conversation where users can engage in discussions around a particular comment. It organizes discussions in a way that users can easily follow conversations, understand the context of responses, and see how particular comments relate to one another, thus enhancing interaction and encouraging dialogue among participants.

This format is popular in many social media platforms as it helps maintain clarity within discussions, making it easier for users to navigate through multiple interactions without losing track of the original context.
