So far the most votes are for "IE can and should be killed". Should is debatable, sure. But I'm interested in how. Because I'd argue it can't be done by anyone not named Steve Balmer at the moment.
And noone can blame business, that it doesn't dare to loose a significant amount of customers by not supporting IE with their website.
It'd be a super long shot, but I'd bet that with some generous donations and a proper campaign, a viral petition could get thousands (possibly hundreds of thousands) of signatures requesting that something seriously be done about IE. Could Steve Balmer and Microsoft ignore hundreds of thousands of people? Sure. Would they? Maybe. They do seem to think they know what's best for everyone. Would it hurt to try? Definitely not.
