The Seattle Times: Business & Technology: Startups to make big pitch at Demo

Another subtle tip of the hat to Vanevar Bush 

At Demo, Trailfire plans to announce a new service that allows people to create and share a path on the Web by using annotations, or marks, that make up a "trail."

Going forward, the trails will be found not only on TrailFire's Web site, but also through other resources, such as a search engine or through ranking tools, such as Digg or del.icio.us. To do so, the trails will have a unique Web address, or URL.
