Paranoia is a specific thing. It requires irrational, unjustifiable fears and a sense of blame or persecution. You're not "paranoid" if you've changed your behavior in the wake of the Snowden documents or if you're cautious regarding the amount of information you share with third party services and devices.

I'm not being pedantic, I've seen a lot of arguments recently from actual paranoid conspiracy theorists that feel smug in the wake of Snowden. I'd hate to see people start to confuse real paranoia with informed caution.
