Isn't it a bit cliché to hate on Internet Explorer?
But it's not without reason. There are a multitude of reasons that web designers dislike Internet Explorer, most having to do with its inability to keep up with modern standards.
For the sites of Orange Gnome, I have chosen to go without Internet Explorer testing for one main reason: it's time consuming.
When I develop a website, Firefox, Safari, Chrome, and Opera typically all display the same, with very little browser-specific adjustments needed. That same site usually needs at least one, often more, stylesheet specifically to meet the needs of Internet Explorer.
This is compounded by the fact that, as a Mac user, Microsoft doesn't even bother to release its browser on my platform. To just test Internet Explorer, I have to boot up a virtual Windows machine. Obviously, Microsoft doesn't care about me as a user, why should I care about them as a developer? For my personal projects, I have chosen not to bother.

I encourage you to try some alternatives:
Firefox, Safari, Chrome, or Opera.
