Web developers building web apps for web browsers typically do not test cross browser compatibility.
They build in Chrome and test with Chrome and then the test of the week they whine about Firefox and Safari.
If true then Chrome is truly the new IE because that's exactly what they used to do with IE.
Some of us still do, apparently the newer generation no longer does, putting to waste all our effort for Web freedom, it is ChromeOS now, Google suceeding where Microsoft failed.
