Mark, touch, history, transience, communication, all things the sign board sediments. As a newspaper's pages accumulate history, a condo's message board holds its neighborhood. There is lives, jobs, wants, wishes, desires attached to a board, fossils of a building accumulating the tacks of people's frontiers, the edges of their presence in the world, leaving notes to the chance of being happened upon, message in a bottle of dryland. Information display systems we find increasingly endearing.
