"We look to media as memory, and a place to memorialize, when we have lost. Hypermedia pioneers such as Ted Nelson and Vannevar Bush envisioned the ultimate media within the ultimate archivewith each element in continual flux, and with constant new addition. Dynamism without loss. Instead we have the Web, where Not Found is a daily message. Projects such as the Internet Archive and Afterlife dream of fixing this uncomfortable impermanence. Marketeers promise that agents (indentured information servants that may be the humans of About.com or the software of Ask Jeeves) will make the Web comfortable through filteringhiding the impermanence and overwhelming profluence that the Webs dynamism produces. The Impermanence Agenta programmatic, esthetic, and critical project created by the author, Brion Moss, a.c. chapman, and Duane Whitehurstoperates differently. It begins as a storytelling agent, telling stories of impermanence, stories of preservation, memorial stories. It monitors each users Web browsing, and starts customizing its storytelling by weaving in images and texts that the user has pulled from the Web. In time, the original stories are lost. New stories, collaboratively created, have taken their place."
