The most amazing thing to me about Trello is that while the software guy in me wants to lock it into a more structured project management tool for say Scrum, it is amazing that with a very small amount of options, features, and metaphors it manages to be a solid tool for a lot of people. It doesn't work great for every team or every situation, but it is a very interesting canvas to paint on (so to speak). It is practically a tool that invites you to come up with clever ways to organize your own things simply because it gives you a handful of smart, simple metaphors and doesn't restrict you too much in how you interpret them. Smart software.
