WeDontSupportIE.com is a site with a simple message: Don’t use Internet Explorer. This is a message I can get behind, however I would not take it to the level they have. Disliking a browser and not supporting it are two very different things. As a web developer, I would never announce that I did not support a browser that still has a grasp on the majority of the market, and therefore is likely to be the browser being used by my intended end users.
Unfortunately, they are very right about IE’s abominable track record when it comes to security and standards compliance. A large part of my time at work is spent modifying CSS and Javascript to work in as many browsers as possible. Of course, jQuery has eased much of this on the Javascript side, but accommodating different browsers is still a huge time suck.
But is it worth it? That is the pertinent question here. I guess another way to ask this question is: Do you want at least half of the people on the internet to be able to view your content?
Any time I am asked to clean up spyware and/or virus infections, I usually find that IE is the only installed browser. Step 1 is telling the user to install Firefox, Opera, or Chrome and use it – after I reformat their hard drive, thanks to their horrible browsing habits and extremely insecure, never-updated Internet Explorer.
I have even seen sites go so far as to only display a Firefox download link when the users browser is detected to be Internet Explorer. This baffles me. Do you really want to prevent a user from seeing your content just because of the browser they are using? Shouldn’t you be honored that someone is attempting to view your content? Shouldn’t the web be all inclusive? Further, when you can translate page views to a dollar amount in ad revenue, telling some users they aren’t worthy of generating money for your site is about as stupid as it gets [update: i was talking from a business perspective. you'll notice no ads on this site (there were a couple google adsense spots before, but i felt it cheapened my goal for this site).].
Is Internet Exploder a thorn in my side? Most definitely, and I think most web developers would agree. But I would never turn a user away because of their browser. That is just bad business.
