So what happens is you surf around. Suddenly a site with some vulnerabilities crops up. O noes, people could steal your deets. The icon changes, you snoop the list (see the screenshot).

The herd immunity starts to kick in. Soon the web is a delightful place (again) full of 'under construction' animated gifs and dancing babies.
