The biggest nightmare right now is internet privacy and security. It's always been a good idea to be careful with one's online activities. There are, after all, a lot of creeps out there who will try to invade your privacy and steal your stuff. The saddest part nowadays, however, is that one of the most powerful perpetrators of privacy invasions is our own government, particularly the NSA. Now they want to not have to go to the trouble to, you know, follow the law.
Come on, y'all. Please don't make me agree with the libertarians.
