I run some fairly popular tech focused sites, I have IE running at 15% on the most popular, down to 3% on the least popular.

At the very least the advice is to take your audience into account, and if you are in this particular sector not supporting ie is a doable tradeoff.

if anyone gives an absolute statement that you should support ie, or you shouldnt support ie, unless they understand both the exact demographics you are targeting, and the internal structure of your company as well as the technical details of your product, they are wrong.
