Everyone has Chrome, FF, Opera, Safari & IE8.
But, rather than IE6 we never test sites on Older browsers.
Why? Because of this: http://www.w3schools.com/browsers/browsers_stats.asp
Still there are people who are on IE5 too, but we never check for them.
I think that everyone who's an avid & dedicated web surfer should have an updated Browser as the older browsers dont have the features which are changing the face of the web.
Slowly, these people we see that websites dont work on their browsers & they will then know that their browsers are old & eventually they will upgrade.
We as the web developing community have the responsibility to update the users on "the benefits of using latest browsers"f2富二代官网入口
