One hour, ten mini-sessions, any topic...as long as it's five minutes long. Pitch your crazy new module, complain about the state of documentation, show how you built your lizard selling site using Drupal, talk about the 5 best modules for organizing profile pictures, dazzle us with strategies for getting work done while taking care of five small dogs and a baby, demonstrate your awesome Jquery menus, show newbies how to review a patch, brag about how you got your users to navigate 70 different content types. As long as it's 5 minutes long, it's fair game. A perfect smorgasbord for getting excited about what Drupal can do.
