==A Fine Vehicle for Pioneering What does Wagn do? From note-taking to knowledge management, from daily todo lists to a public directory of company and product information, from back-of-envelope ideas to databases, and from rolodex to operations manuals: Wagn covers a lot of ground. It's a wiki you query, an on-the-fly community database, a formatting system, an application platform, and a playground .... all in one.
