title: Google Reader API Linking reader's User ID to a Google Account
body: <p>I am developing a web application that heavily utilizes RSS feeds.</p>
  
  <p>I have found you can query Google to get statistics and analytics on your RSS Feed (very useful, if you administer RSS feeds, you should check it out! <a href="https://stackoverflow.com/questions/1635141/retrieving-google-reader-stats-for-rss-feed-and-items">Retrieving Google Reader stats for RSS feed and items</a>)</p>
  
  <p>Now that I have a method to determine a list of Google Reader User Ids that like a feed item, I would like to know how I could use this User Id.</p>
  
  <p>Specifically, is there a way I can link a User Id to a Google Account - if they are logged in through a web interface like Stack Overflow does?</p>
  
  <p>If this is not possible, what public information can be gathered about a particular Google Reader User Id? Is there documentation on this API? (note, I am not looking for Google Reader API, which, from my understanding, allows you to build your own RSS Reader)</p>
