Yeah. Right. Customers have nothing to do with business. (or like you said "screw them")
I'm not sure I'd want to work at a company so out of touch with reality.
That's ok because I am pretty sure you don't work for any company.
I evangelize standards -- something Microsoft has a problem with when they don't own them.
About 70% of users use IE. Most corporations us only IE. Most Internet business software only supports IE. But as you said earlier "screw them". HINT: if you ever do get a job in the industry - customers don't pay for W3C standards, they pay for content.
They pay for content that can be rendered on their browsers. If that means it takes me more time because of IE's poor CSS support, or if I just don't make the site as good as I could have because I've dumbed-down the CSS for IE, then fine -- they're paying for it.
BTW, I started getting paid for doing web sites about the same time that BillG realized the WWW exists. I was still doing it five years ago when anyone willingly hosting on IIS was considered an idiot, and I'm still doing it now when Microsoft finally has decent server software, but a horrible client.
