WagN is a deep merger of wiki and tagging—not just a wiki with tagging, but wiki and tags all mashed up together. WagN can do everything a regular wiki can do- but it can also handle data in a way that regular wikis can’t. * WagN is made of cards A card is a chunk of information. * Cards can be connected Whenever two cards are related, you can “connect” them, creating a new card to explain the relationship. * Cards are named with tags A tag is basically just a word or phrase. Every tag has a card that explains it, and every card has a title comprised of one or more tags. A simple card's title is a single tag, while a connection card has a title built from multiple tags.
