Password strength continues to be a dominating weakness in terms of security. Crackers get smarter, processing power increases resulting in the need for longer and longer passwords.
We actually way past the place where the notion of a single word is sufficient to protect most anything on an untrusted network. Enter the idea of a "passphrase". Makes a lot of sense.
"We're #1" is a strong password compared to many. How about "Can't touch this!" orĀ 
"Phone Home 123-4567". The point is that you can more easily remeber phrases than 14 characters of randomness and can be cryptogrpahically superior.
