- By following a list you would be notified when a certain events happen, such as a new item being added.
- When a list creator updates their list, they would be given the option to trigger a notification to followers or not. This would allow them to make minor changes and fix typos without triggering a notification.
Could it be that people may not want to follow a complete list but a subset of entries on a list? ¯_(ツ)_/¯
