Just as I was about to sign the petition (I've only signed 1 other one before to revoke the Westboro Baptist Church, lol)....I plan to run a "successful," startup someday soon, do you think it's safe to sign a petition (esp when I don't believe Aaron Swartz's demise was self-inflicted).
I plan to run a startup too, and frankly having to wonder whether some types of pro-civil-liberties speech are "safe" is a good indicator of how far off the track the USA has gone.
