title: get data from page that a url points to
body: <p>Given a Url, I'd like to be able to capture the Title of the page this url points to, as well
  as other info - eg a snippet of text from the first paragraph on a page? - maybe even an image from the page.</p>
  
  <p>Digg.com does this nicely when you submit a url.</p>
  
  <p>How could something like this be done in .Net c#?</p>
