I'm actually surprised at how low the IE number is - for government websites. Obviously you can't compare it to the traffic on HN or Techcrunch, where like 70 percent must be on Chrome and 5 percent on IE, but seeing how some analystics sites still put IE at 50 percent market share, I think that's quite impressive.
Or NetApps' market share numbers are crap, and StatCounter's (and others') numbers are a lot closer to reality - which is that Chrome dominates the web browser market.
