Major web sites like Wikipedia and Boing Boing have gone dark today, while other giants like Google have announcements on their pages about the protest. GIS sites like Bill Dollins and Spatially Adjusted have also gone dark. Those sites have informational videos and forms for people to get involved with the protests.
