If you only fire up Tor when you want to do something secret, you're leaking information about yourself that could get you caught. A Harvard student who emailed a bomb threat got tracked down this way. Obviously I don't support one's right to email bomb threats, but the principle is the same, the investigation narrowed down to him because of the exact time his Internet connection connected to a Tor relay. So I second your call for us to run our own relays, full-time.
