Kind of funny how every IE vulnerability is blasted my non-IE users and any non-IE vulnerability is someone spun and looked upon as a good thing. A very bizarre social phenomenon I would liken to the drinking of some magic koolade.
Can't wait until all these IE haters go through puberty, graduate high school, go to college, get a job in the real world and have no choice but to use IE in Corporate America.
Everything is vulnerable. To assume otherwise is where you get into trouble. And I agree that if (not when, if) an alternative browser to IE gains in popularity enough that anyone actually cares, there will be an increase in issues identified and vulnerabilities against the non-IE browser.
