I hope this is a troll, I really, really do.
I've developed web pages, fuck IE to hell. Fuck it. Fuck Trident and Fuck Microsoft. Fuck it.
If you use IE kill yourself.
Seriously.
It's not a "nightmare" for devs, it's more like, "I feel like wasting the entire week doing something entirely pointless, let's make our web code IE compliant because they couldn't realize how to incorporate proper opacity settings and a y-axis. While we're at it, let's readjust the entire website so that the pixels match up in IE but no other browsers."
e: Fuck you. Fuck IE.
