What percentage was it when everyone collectively decided to stop supporting IE6? 20%? To me it’s less of an absolute percentage and more of a function of how much extra effort needs to go into it, and whether the usability of the rest of the product needs to suffer. I’ve seen potentially useful features nixed because they can’t be made fully compatible with JAWS, which seems silly to me.
