I created this app because I regularly needed to send lists to friends or colleagues. Usually this resulted in create a todo list and inviting them to collaborate on the list. This was quite a burden, so I built something that made it easy to create and share lists with other people. Since all lists are URL addressable, I figured it could be cool to be able to see other lists and let people "star" them, and then the most popular lists bubble to the top of our explore page.
