6.4% of the 14.3% of people using IE use IE8, so that’s just under half
Poor choice for statistics.
Plus XP still has a very wise user base and IE8 is as high as they can go, therefore until XP dies out (which will be a while due to companies not upgrading their networks) IE8 will always been to be dealt with.
It’s developers fault. As long as we all try to please IE8, things will never change. It should be the other way around, people to notice the visual difference in a site between a moder browser and a junk, then update it and enjoy quality. But noone risks to lose clients/buyers/visitors, I undestand that. It;s a vicious circle. Only time can help.
