It appears WWI of cyberwars has begun. It seems to be a fair fight, with weapons of choice being Distributed Denial of service attacks. The main casualties will be financial in nature, but will deeply affect how the world will operate in the future. The expectation of "complete" privacy has been eroding considerably, and can only be considered a transient phenomena (this conversation is secure for now - if I don't record it, it loses usefulness. If I do record it, there is an unknown probability that it may be leaked somewhere in the future - hopefully it won't bite us too hard, and will fall in the hands of our friends and not get exclusively sold to our enemies without our knowledge)
This is also the dillemma I (or anyone) has with their own private and intimate emails to friends. I have got into the habit of self-censorship just as much with my private emails as I do with FB or this Blog. There are still a few things I say and talk about verbally that I would not put into writing.
