I recently found a useful app called, Cortex, which allows you to share links, articles, videos, images, music to your friends and family across the web. Cortex is very easy to use and is a fast way to share any content you find on the Web with your followers in Twitter and friends in Facebook. In order to use Cortex, you need to install the free Cortex extension on Google Chrome. Then, find information you want to share on the Web, click and hold for selection options to share. Cortex chooses header text and shortens URLs. It allows you to share just an image or specific selected text. In addition, Cortex lets you track your history of shares.
I have enjoyed using Cortex so far. The Cortex interface is unique and is fast and simple. I wish it will work with my favorite browser, Firefox. Right now, you can share to Facebook, Twitter, Tumblr, and Instapaper. According to Cortex, more options will be available soon.
