youRhere – Enable Readers To Mark & Share Articles
When reading a long article on the web, we sometimes leave it in the middle to continue later (an e-mail arrives, door rings, etc.) and have difficulty on remembering the line we were at.
Once the jQuery version is installed on a web page, a marker follows the mouse besides each line and double clicking any line gets highlighted + stored with HTML5 localStorage. So, you can easily see the marked line anytime, even if you have closed and re-opened that URL.
The Chrome extension is for yourself to get the functionality on any web page without the need for the jQuery plugin being installed. It also offers a "social share" feature.
