title: How did Evernote implement their Clearly Chrome Extension?
body: <p><a href="http://www.evernote.com/about/download/clearly.php">Clearly</a> is a <a href="https://chrome.google.com/webstore/detail/iooicodkiihhpojmmeghjclgihfjdjhj">Chrome extension</a> developed by Evernote which makes blog posts, articles and webpages clean and easy to read. Clearly eliminates all distractions (header, footer, navigation, ads ...) from page to have seamless view! How does it work under the hood taken in consideration that page structure differs from site to another one?</p>
