Haiku Deck (@HaikuDeck) is becoming one of my favorite Internet marketing tools. As I mention in the linked post great tools make good Internet marketers great and great IMers fantastic. Haiku Deck, a visual storytelling tool and presentation tool, is a GREAT and very cool tool.
Even better? You don't have to learn a whole new way of thinking to use Haiku Deck. The UI is intuitive and build FOR marketers by marketers.
