Being informed of risks is not the same thing as frightening someone. I 
I was  suggesting that  you expose  them to the  *true* risk  of having 
their account compromised  due to insecure passwords. If  the risk they 
incur is merely that someone might obtain access to their private stash 
of  family  photos, then  they  will  know  how  secure to  keep  their 
password.                                                               

And yes, if  the system contains high risk material,  then I would argue
that an  extremely difficult password written  down on a piece  of paper
and  stored in  a wallet  is very  secure, compared  to a  weak password
policy which  allows people  to use dictionary  based passwords.  It all
depends on  where the  system is  located, how it  is accessed.  I don't
think there is a universal password policy that applies everywhere.

You might  be right on  this point. In this  case, you should  require a
minimum of  32 characters,  that way people  will naturally  start using
passphrases instead of passwords (you  can help saying ``pick a sentence
for your passphrase.''
