IE sucks. So much so that SecurityFocus columnist and regular Microsoft apologist Tim Mullen even admits as much. To me, what's shocking isn't that someone is saying that it's time to abandon IE, but even Tim says so - although he only suggests that MS split IE into a regular and "Enterprise Edition".

I'll go one step further (as many other security professionals have) and endorse the Browse Happy campaign to switch to an alternate browser. I can say from personal experience that even large corporations and government agencies are seriously considering switching away from IE, or in one case, already have. (usually to Firefox)
