UbuWeb Will Join Reddit’s January 18th Blackout to Protest SOPA If SOPA passes, you can kiss UbuWeb goodbye. Remember, the web won’t be this way forever. Don’t bookmark. Download. Download. Download. Everything on Ubu is downloadable. Hard drives are cheap. Grab what you need. Don’t trust the cloud. Stop SOPA
