after 10 years~ of lurking, your comment was the one that encouraged me to finally sign up.
I agree with you completely. Let's not joke at the capabilities of a trillion dollar organization focused on "cyber".
If you are fortunate enough to be a United States citizen who gets up and contributes to society on a daily basis -- you will never have anything to worry about. The NSA won't care anything about your dealings on the internet. Everyone can safely get back to their weird browsing habits and making lame comments on youtube -- no one is watching, because no one cares :)
