Just don't be one of those people who makes website that turn their nose up at people using IE. I saw one that said:
"I see you are using IE. This site was tested with Firefox browsers. IE does not correctly support W3C standards. If this site shows up incorrectly, you should browse it with Firefox."
That's just bad practice. Firefox also doesn't support all the W3C standards (just more than IE does), and it's utterly ridiculous to tell people what browser they should use for your site. Does he really think I'm going to go and fetch Firefox just for his site? All people like that is strengthen my resolve to avoid Firefox.
