Do you really believe your life and freedom are in greater danger from visiting edwardsnowden.com, but not from, say, hanging out on Hacker News? Or following Edward Snowden's twitter account along with a million other people and counting? Or visiting any site hosting any story related to Edward Snowden? Edward Snowden has done an interview with John Oliver, which presumably means everyone visiting any site hosting that interview is also on a permanent NSA watchlist. He was on the cover of Time Magazine, so all Time subscribers are also on a permanent NSA watchlist.
Yet despite apparently almost everyone everywhere being under constant surveillance by the NSA at this point, there appears to be no global chilling effect, apart from that caused by people warning about a global chilling effect.
Don't let your need for bias confirmation and your desire to play the victim-protagonist in a dystopian narrative cause you to act with more caution than necessary.
