I'll go ahead and say it right up front: No self-respecting person who knows anything about computers uses Internet Explorer. The only people who use it are the people who don't know that you can download several other web browsers, completely free of charge, which will do so much more than IE does and do it faster. These are the people that buy a computer and know they can click on the little picture that looks like a little "e" and get on the internet to look at pictures of Sally's new baby. That's all they know. Of course they use IE, because they don't even know what a web browser is. They don't care about features. They just want to see the pictures.
It's gotten fairly ridiculous. The three (other) most popular web browsers, namely Firefox, Safari, and Google Chrome, have functionality that IE can't even touch. By that, I don't mean features like plug-ins, window themes, and thumbnail views of your most visited sites. I mean the functionality of being able to view web pages properly.
Let me give you an example. In recent months, I've begun a new web comic. I know, I know, big deal. Everybody's nerdy cousin has one. Unfortunately, I'm not quite nerdy enough to know a ton about web design yet. Therefore, I've gone and looked at a few manuals and tutorials on CSS and how to properly work with WordPress. Quite often, I've come across the phrase "but it doesn't show up in Internet Explorer." Not only have I seen that, but I've read complaints from people to that effect.
Let's break this down, shall we? This means that there are web standards that are adhered to by every single other web browser in existence except for Internet Explorer. This also means that all of the fancy code that I've put on my website won't show up, and so it looks extremely ugly, doesn't show up, or even renders the page completely unviewable when viewed in Internet Explorer.
Hence my question: Why do people still use IE? The only answer I can come up with is that they don't know any better. If they don't know any better, then they won't care if my website is ugly. That's fine. If they don't care, then I don't care.
What I have found absolutely no answer for is the complaints from people about things not showing up in IE. If they're webmasters and they have clients who only use IE and stubbornly refuse to use anything else, then fine. No need to get in the way of your revenue stream there. However, if they're complaining because they are stubborn and don't want to use anything else, then shame on them.
There is no worry about money. All web browsers are free. There is no worry about losing settings or bookmarks. The good browsers let you import those. There is no worry about interface. They all look and feel pretty much the same, apart from tab behavior, but that's easy enough to get used to. Just make the switch. It's painless. It gives you a better browsing experience. Educate those who don't know better. Teach them that they can, and should, click the little fox going around the globe to look at Sally's pictures, or the compass, or the... strange rainbow circle thing. Just don't click the little "e."
