In my defence, I wrote that before Snowden (the events, not the person). In fact I absolutely agree that encryption is probably ineffective if you're trying to hide stuff from a government.

However the main use for encryption is to store your journal on an insecure medium such as Dropbox, and I believe encryption is still the best way to keep your data from companies you don't trust.

(Then again, after Condoleezza Rice got on the board of Dropbox, I'm not so sure anymore.)
