“The Smithsonian’s Cooper-Hewitt National Design Museum is about to take its Web site where no museum has gone before. Where that is isn’t absolutely clear, but it merits getting excited about. The so-called ‘online national design museum’ promises to open the museum and its vast collection to visitors anywhere in the world. What’s more, if development can keep up with vision, the site will turn museumgoers into participants in a bold cultural experiment.” Specifically, visitors to the site will be able to add and manipulate content, Wiki-style. Will it work? No one really knows.
