One slightly positive thing to come of Snowden's revelations, was a bill put before congress to rein in the NSA's surveillance. The bill did NOT pass, unfortunately. But the closeness of the vote has given hope to the American Civil Liberties Union and others who are trying to take action, that in the future such efforts may result in a change.

I am feeling very pessimistic right now about the NSA ever changing its tactics, but who knows?
