The Usage of different browser verions is very interesting for me. Internet Explorer 6 causes many problems in Webdesign as it doesn't handle CSS and HTML as it should.

As Google has stopped to support Internet Explorer 6 I hope the decline of its usage will speed up.
Here are two cool websites, that track browser versions:
- Browser Wars
- Usage share of web browsers
- Comparison of web browsers
- Mozilla Firefox
- Google Chrome
