Anybody looked at http://www.dailydot.com/politics/flowchart-avoid-nsa-online/ http://www.dailydot.com/politics/flowchart-avoid-nsa-online/ (linked by Schneier in the blog post)? Isn't that a little drastic? The fact that my 4096-bit-gpg-encrypted mail has been stored by them doesn't mean my communication is pwned: the idea with strong encryption is exactly you cannot trust the transmission channel! And besides it doesn't take in account OTR for chat.
