Tor is an irrelevance in the UK
If you run an exit node the UK government will shut you down using the best Daily Mail tactics available. Count the exit nodes in the UK compared to say Germany or Austria.
Just for fun, install the Tor and Privoxy clients, use Google. You'll get a different view of the world. Without it you get the view some spod in the government deems fit.
China isn't the only country being censored.
Make July 4th Exit Node Day in the UK.
