Bless you, because it was while trying to figure out if I agreed with you that I looked up "sarcasm" in Wikipedia and found this awesome quote:
Fyodor Dostoyevsky, on the other hand, recognized in it a cry of pain: Sarcasm, he said, was "usually the last refuge of modest and chaste-souled people when the privacy of their soul is coarsely and intrusively invaded."
Beautiful. So, based on that: If what I wrote wasn't technically sarcasm, that's not because I wasn't trying. ;)
And now I'm afraid I must reiterate my clearly-signalled disinterest in yet another lengthy debate about Google's privacy policies. There are plenty of older threads on HN that cover these things, and this week I have more urgent things to do, like try to make up my mind whether or not my past and future YouTube viewing history is bound up with the privacy of my soul.
