title: Find the number of times a tweet has been viewed
body: <p>There have been quite a few number of start-up pertaining to analyzing Twitter data. There is <a href="http://crowdbooster.com/" rel="nofollow">CrowdBooster</a>, then there is <a href="http://klout.com/" rel="nofollow">Klout</a>, which use Twitter data to tell the user their True reach. </p>
  
  <p>I have got the following two questions: </p>
  
  <p>1) Is there a way to find out who has viewed one's tweet, or the number of people that have viewed a tweet. Crowdbooster claims to tell you how many impression one received per tweet. How do they do it? </p>
  
  <p>2) Thousands and thousands of links are shared each day on Twitter. Can we find out which user has clicked the link in a tweet?</p>
  
  <p>I have looked through Twitter API and some of the companies that have licensed Twitter's Firehose, but have not found anything that meet my needs. </p>
