Making it easy for the bad guys

Seveny five percent of all users use the same password for email and social network sites, according to a story in Security Week magazine, citing a study by Bit Defender.  Want to bet a good number also use the same password for their bank accounts, credit cards, Starbucks card, and every other web site?   

We all probably trust the security of our bank, but what about that website where you had to register, then take a survey to get a chance to win an iPod? Who's running that site?  Did they ask you to pick a user ID, enter your email, and select a password?  And did you use your "usual" ones?

When you say it out loud, does it seem like a good idea?
