I was reviewing Zscaler’s State of the Web – Q2 2010 and was surprised to learn that Zscaler is seeing 16% of web traffic is still using Internet Explorer 6! Since Zscaler can be configured to prevent the use of IE 6, my guess is that IE 6 usage in the general population is even higher.

There is good news though – the trend for IE 6 and IE 7 is down and IE 8 is up, but IE 7 is still the most used browser by far at 25%. Firefox is second at 10%.
