As we engage our students (and ourselves) with more and more online text, having an interface without ads, pop-ups, comments, and other distractions is becoming increasingly important. There's a ton of great stuff out there, but focusing on the text itself can be a challenge.
One option for getting an uncluttered version of a website is the Readability Chrome extension. This extension, when activated on a web page, extracts the core text & images and gets rid of the other junk (bookmarklet tools are also available for Firefox, IE9, and Safari).
In the CNN article below, bringing up this article from the main page also brings up videos, animated ad content, reader comments (some of which are inappropriate), and side bars to other articles. In addition, it takes a while to load because of all of the extraneous content.
Clicking on the Readbility extension icon gives you the option to "Read Now." Choosing "Read Now" cleans up the view for easier (and less distracted) reading -- no ads, videos, comments, or sidebar content.
