IE's demise makes "cross browser" even more important

Here is a great article on SitePoint about how IE's decline is making crossbrowsertesting.com important for web developers.

As browser parity nears (at least in terms of user reach), cross browser and cross platform functionality is becoming more and more important.

Web developers will end up with more work for all of this of course. Which is why we came up with a site for browser testing in the first place (we are web developers!)
So when IE10 and Chrome4 are in heated competition and you need to test a web page we will be there!
