I quite like the idea of Tor and the fact that it can be used to bring down corrupt governments and expose all sorts of wrongdoings. But I had a quick look around and quickly delete the browser off of my PC, because the onion is also a hive of guns, drugs, and child pornography. Put that up to human nature, I guess. The latter will be why the US government starts eventually cracking down on and disrupting the network, I expect.
