Re: Is the padlock a page security score?

At least the weather forecast is based on the right factors though. All of
the things we're looking at seem to be "Is my connection to the server
secure" / "Am I connected to who I think I am". Sure, EV adds a bit more on
top of that, but basically we're still stuck at the same question that SSL
answers, which is "Who am I talking to, and am I doing so securely?"

It's been a *long* time since I've heard anything about someone's credit
card getting stolen by a MITM attack. It's very often that I hear about
credit cards getting stolen because a site was hacked, or because of poor
security practices on behalf of the site.

It seems like the first question (SSL-esque question) is really the only
thing we can answer, but it's also the least useful thing to answer (IMHO)
and we are doing a disservice to the user. It's the equivalent to saying "Is
it going to rain" and making your prediction based only on the barometric
pressure, without looking at any storm fronts etc. We're leaving out the
most important information, and still expecting the user to make a decision.
This seems wrong.
