I'm going to say what I've been saying since sometime around 2004...
Using IE as your browser is the equivalent of stripping naked, painting a bullseye on yourself in glow-in-the-dark paint, and running into the jungles of Vietnam in the late '60's screaming "shoot me, shoot me!" so far as security is concerned. They do not have a history of security that could possibly result in anything resembling trust, and older versions have unpatched gaping security holes big enough to sail the USS IOWA through.
ANYONE DUMB ENOUGH to use it for anything more than testing compatibility of YOUR OWN CODE... well, deserves what they get; as it WILL bite you in the ass sooner or later.
That said, it's not like Safari is any better -- after all, what's first to fall at every Pwn2Own competition of the past DECADE?
... and that said, at least nobody here (that I noticed reading the thread) said "wait, people still use IE" or "who cares, hasn't it lost 60% market share" or any such nonsense like you'll find on pretty much EVERY web development forum right now; Love that one which crops up every time a topic like this comes along; web developers try to use it as an excuse for not supporting certain browsers when the conclusion of "market share" is usually one big fat card-stacking lie.
See... sure, IE has dropped from 95% of the market in early 2004 to anywhere from 25% to 50% of the market depending on who's numbers you use right now -- but the number of people online has grown from 750 million to 2.9 billion users in the same time period. Now I'm no mathematical genius, but last time I checked 95% of 750 million is 712 million. 25% of 2.9 billion is 725 million... Guess what, while allegedly "losing" 70% of the market they gained 13 million users -- meaning they haven't lost jack ****.
Sad as it is, there are more people using IE today than there were back when IE 6 was "the only browser that mattered"!
One of those cautionary tales of "don't let people use percentages to lie to you" as a percentage, particularly when used for "share" means absolutely nothing without asking "Yeah, but a percentage of what?"
Still, anyone still using IE probably doesn't know enough about computers to be making choices on what software to use -- but NEWS FLASH, that probably describes 90% of users in first-world nations. Even sadder, many users in third world nations know more about it as they have to so they can even get online in the first place.
