Google's Chrome Canary web browser is cool for two reasons. First it contains the most experimental features that you can try months before they get to the stable release and made available to everyone. Second, you can run Canary on the same system as your normal Chrome browser without the two sharing any profiles, themes or preferences.
Canary now includes a "Distill Page" option (highlighted in the picture below) which can be turned on using the instructions provided at the link to the ZDNet article. The purpose of this feature is to render content such as news articles without all the distracting advertisements, making a nice clean "Reader Mode".
