First:
Thank you Snowden for introducing Privacy as a Banner issue which makes things like competing on providing greater privacy a "Business Differentiator".
Before the disclosures there was only a murmur of privacy violations that too only amongst the tech literate. Yesterday the old guy manning the register at a store said "Now they can't track you when you pay by cash" to the customer in-front of me.
Second: What a lazy-ass way to dragnet everybody and get stuck with huge irrelevant data! If you really suspected some one, the govt. should be able to convince a judge to get a "tap&gag".
