This varies widely by industry. We sell software to insurance companies. 40% of our pageviews are IE8. Sure, we can choose to ignore those customers, but in our world that's a lot of money to leave on the table.

I'm not saying I think everyone should be building for IE8. I wish we could stop. But it's also not always just as easy as saying give up 5% of your potential users. The HN crowd is so often consumer focused and incredibly out of touch with the enterprise markets (this is not an argument against the parent comment, but an overall trend I notice on HN).

as a supporting piece of anec-data I worked for an education startup in the uk - and we had to support IE 6 (six) as upwards of 50% of our userbase of high schools had locked in contracts with suppliers like RIM (not blackberry) and could not upgrade without incurring costs - which meant it did not happen.
