I used it once to try and find an anti-government website, something like the anarchy cookbook but practical and a forum, and I found a Tor site that looked normal but just scared the bejesus out of me. Never used Tor since. Well, I did get forgetful in college and tried to Torrent through Tor because I wanted to not get arrested for pirating or kicked off the uni network. Brain-damage and memory loss sometimes go hand in hand with schizophrenia.
I am a paranoid schizophrenic - who has been paranoid of the government for a very long time - I don't use Tor. I will NEVER use Tor. I would rather be arrested for anti-government writing or something than use Tor. I would rather be charged with promoting terrorism because of my own server on my AWS account than use that goddamn evil network. At least I would include instructions that indicate Tor exit nodes as viable terrorist strikes.
