Evernote, one of my favorite web apps (along with Google's many apps), just announced a very cool new product.
Evernote Clearly is a browser extension for Google Chrome (other browsers will be added soon) that allows you to read online with less distractions. You simply click the extension and it hides all the distractions from blogs and articles, allowing you to read with less distractions and more easily.
When you click on it, it slides in, showing you a new view of the page without any ads, links, or navigation. When you are done reading, simply click the return arrow and Clearly slides out of the way allowing you to continue browsing the site normally.
