Woody Guthrie used to have the words "This Machine Kills Fascists" on his guitar. I've often thought that that would be a fine sticker to put on Internet-connected computers. The free flow of information is anathema to authoritarians.
Need proof? Reports are coming in that Egypt has shut down all internet access, as protests continue against the U.S.-backed regime of Hosni Mubarak.
That, I think, is pretty much a sign that the cat is out of the bag, and that this regime's days are numbered. (The question, though, it whether what replaces it will be better...)
