I work at Trello. We actually don't think of Trello as Kanban. Trello at its core is a collaborative list of lists. You can use Trello to implement a Kanban workflow but Trello is not an implementation of Kanban. A lot of people use Trello for things like to organizing their soccer teams where there isn't a hint of Kanban -- each list could be a game and people add themselves to indicate that they want to play.
