Not that this is really news, I mean who in their right mind would be using this software but it still needs to be said.
Internet Explorer 6 was once on top of the world despite being a terrible web browser (even for its time) with poor rendering skills and security.
However Microsoft has report that in the US, Internet Explorer has dropped to below 1% usage share according to its source NetApplications.
According the the IE6Countdown.com website, Australia continues to sport a 1.6% market share. While it's a low percentage, that's still I high number of users.
If you know someone that is or might be using the browser, for the love of God, update them to Internet Explorer 8/9. Or even better, get them to use an alternate browser.
