This chart shows the change in browser usage on InfoWorld.com from November 2004 to March 2005.  Firefox increased in that time from 21% to 30% at the expense of IE usage which dropped from 72% to 66%. 


The Firefox usage isn't a surprise given the technical savvy of our audience.  But I am a bit surprised to see how few Mac users we're serving.  This chart below shows that less than 3% of our audience is Mac-friendly...strangely, somebody out there is still using WebTV. 

Could this be an indicator of Mac presence in the corporate IT ranks?
