Hi all,

This whole discussion is subjective.  What is useful for one person could 
very well be useless to someone else.

An analogy - weather forecasts about the possibility of rain today.  Does 
such a score indicate whether I will get rained on?  No.  Does it help me 
decide whether or not to wear a hat or carry an umbrella?  Yes.  There is 
no way that people other than meteorologists (and some would argue, even 
them) will accurately interpret isobars, cloud patterns, and doppler radar 
to determine whether it will rain.  But people can get a feeling for the 
chances of rain based on a 0-100% estimate.

I think the same is true for the notion of a page security score.  Does it 
imply that the user will definitely, without a doubt, not get "taken"? No. 
 Does it give the user something with which to make a choice?  Yes.  In 
this light, I still feel that page security scores are good things to 
consider.

I would ask the same question about a binary indicator.  The padlock does 
not mean it's safe to enter a credit card.

I still don't understand what anything beyond a binary result is supposed 
to tell a user. I'm on a site with "Medium" security - what does that 
mean? Does that mean that I should give them my credit card or not?

Maybe there is an opportunity to associate "High/Medium/Low" or
"Strong/Medium/Low" based on page security score with the padlock.
