title: OmniAuth to extract full profile data from LinkedIn
body: <p>I'm loving the ease of OmniAuth, but I'm having a hard time connecting the dots on making additional api calls after I receive the token back.</p>
  
  <p>I'll use LinkedIn as an example, but it's not LinkedIn that's the issue, more so my lack of  understanding on how to make subsequent calls after I have authenticated.</p>
  
  <p>I can make the request to LinkedIn and authenticate just fine.
  Then I get the hash back and it's completely populated.</p>
  
  <p>Now I would like to call LinkedIn back and get my complete profile data or maybe a list of contacts. How do I do this? Will I need the oauth gem after all?</p>
  
  <p>I'd prefer to avoid app specific gems because I will have to make the same requests to twitter and facebook.</p>
