Stephen Haunts has a nice post on remaining private on the Internet. It's reminiscent of the Prism Break web page that I've written about previously. He talks about some of the utilities that you can use out of the box to help maintain your privacy.
Haunts discusses Tor, GnuPG, Tails, TrueCrypt, Silent Circle and other utilities that should be in your toolkit. Take a look at his post and, of course, the Prism-Break page. If we all started using these utilities, privacy in the Internet would increase and we'd all be better off. Except, of course, the NSA.
