A symposium on art in digital media concluded Saturday with a roundtable of critics, historians and artists at the Berkeley Art Museum. While the internet may have buzz, here – just miles from the i-epicenter of Silicon Valley – the symposium’s 15 panelists almost threatened to outnumber their audience. And though David Ross, director of the San Francisco Museum of Modern Art, likened the artistic impact of the internet to that of the advent of photography, the panel could hardly even agree on how to define internet art. – San Francisco Chronicle
