Yes, they Use IE 6 Still...

Big huge article, http://www.techzoom.net/publications/insecurity-iceberg/, on how users are not keeping browser security up.

I think the bigger take home message is this: 41% of your users can't do whatever only became available in the latest version of the browsers.

For example, don't assume everyone has a nifty tool to pick up your RSS feed if you don't tell them it's there because Firefox will automatically notice it... What if they use LiveJournal and IE 6? They will never know it's there....
