title: How to read the first few lines of a website
body: <p>I am trying to implement a feature to your web application, in which if a user saves a website's url, it is stored and displayed in the library. Now when a web url is saved in facebook, the first few lines of the webpage is also displayed. I also want to implement a similar feature.</p>
  
  <p>I am using Ruby on Rails. I tried using the .load() method of jquery, but using that I am only able to retrieve description of pages which are in the application. I want to save a url in my app, eg, "api.jquery.com/load/";, and while displaying the list of urls, I want to display a description of the page, like its shown in facebook when you enter a url in the status update </p>
  
  <p>Any suggestions on how to do it?</p>
