1. It is more vertical. Allows for deep search with filters.
2. Ditto. It uses hashtags, forward slashes and bangs. All with a different functionality.
3. I'm up to my neck in machine learning to improve this.
4. It allows for you to search your own posts. Yes, you can post to Nuuton. No, its not a social network.
5. It allows tagging with hashtags. Say #pizza #recipe.
