I use it as password hint if I can (e.g. make it show the first character of my password, I'll remember it then). As answer I enter like 50 random characters which I don't write down or remember or anything, since I should simply know the password or use my recovery e-mail.

The problem is that most sites won't let you set your own question. More about my idea on security questions: http://lucb1e.com/!65
