People will just use OpenDNS to bypass ISP filtering. There is very little ISPs and governments can actually do to stop people from doing what they want, unless they get OpenDNS shut down.
With the way governments react to file sharing, you would think the people doing it were murderers, rapists and carjackers. Why not go after violent criminals and leave the small time vices alone?
I never bought into cloud computing for a second. I don't like the idea of all my data being stored remotely and I can only get to it when I'm online. I could maybe see it if I traveled a lot, but I don't.
I think cloud computing will take off like a lead balloon.
