I'm a fan of KeePass for Windows or KeePassx for OSX/Linux. It's a password database that autogenerates passwords and allows you to copy and paste them into websites. Makes it easy to have unique passwords for each site without having to remember them all.

The main problem, of course, is that you really have to protect that database. If your computer has been compromised with a trojan/keylogger, an attacker could get a copy of both the database and the password to unlock it, giving them all of your passwords for everything.

@swhitney:
ebooks from most online vendors do not expire, but some publishers have used password-protected PDF files with built-in expiration dates. I recall an Ecology class I had to take a couple of years ago that used such a PDF file. It cost as much as a regular textbook, and after 4 months the password would expire and you could no longer access the content. Was not too pleased with that.

@grove600: "The types of people that enlist aren't NPR listeners. "

I enlisted in the military, and I listen to NPR. From my experience, the people who enlist are just a cross-section of the people of this country -- no better or worse or redder or bluer.

That being said, if NASCAR truly bleeds red, white and blue you'd think they would be open to supporting America's military recruiting needs in hard financial times with or without an 80 million dollar government subsidy. But maybe not ...
