By default all lists are public so others can read them, or even edit them wiki-style.

Argue about favorite songs, plan a night out with the girls, let people RSVP to your event, or make a family Christmas list for Santa..

...or keep it all to yourself

You can make lists private so they can only be seen and edited by you. This is great for to-do lists, like groceries or work items, or just quick reminders.
