title: Tumblr OAuth API - How do get user info?
body: <p>I've managed to post to tumblr via their OAuth API. </p>
  
  <p>Unfortunately I cannot read posts because the endpoint for reading is <a href="http://you.tumblr.com/api/read" rel="nofollow">http://you.tumblr.com/api/read</a> (with "you" being the user's username), and I cannot find any method for getting the username.</p>
  
  <p>Making a call to <a href="http://www.tumblr.com/api/authenticate" rel="nofollow">http://www.tumblr.com/api/authenticate</a> is supposed to return user info, and the call is successful, but response['body'] is empty.. Any ideas? </p>
