The only way to avoid technical surveillance is to keep everything sensitive away from email or phone calls or instant messages. There is no way to avoid being the target of the NSA and CIA if they really want to get your data. None at all. The NSA and CIA are creating these techniques against countries such as Russia, China, and Iran with devastating success. (Look at the Iranian nuclear weapons program getting hacked by Stuxnet.) You have no way to avoid the hacking of your data if they are really set in doing it.
Pretty much this. Ergo, if you are intent on inviolable secrecy, you wouldn't be posting on ye olde green line site... nor any other. Who then, is willing to give up the internet and the freedom of speech to ensure no measure of antiestablishmentarianism viewpoint is uttered and recorded?
That I can still post my POV freely from the south side of somewhere without being erased by a midnight death squad is proof enough that the battle for your freedoms is not yet lost.
Vote for candidates, serve on juries, impress the importance of participation on your sports-distracted friends... do what can as one of the minority who can still afford to pay attention
