title: Twitter API: count followers, count total retweet, and retrieve RSS feed of someone's twitter page
body: <p>I am new to Twitter API and only know that we can pull someone's
  Twitter feed from Twitter through RSS feed on that person's Twitter
  page/ profile.</p>
  
  <p>But, how can I pull more information of that person's Twitter page?
  For instance,</p>
  
  <ol>
  <li>His/ Her followers.</li>
  <li>Total of his/ her retweet items.</li>
  </ol>
  
  <p><a href="http://www.qapture.net/" rel="nofollow noreferrer">http://www.qapture.net/</a></p>
  
  <p>There are a couple of interesting things I still cannot figure them
  out how they did this website,</p>
  
  <ol>
  <li><p>If you compare the particular person's twitter feed on this website
  with that person's twitter page, some of the items are pull in qapture
  website, but some are not, so I think they must have select certain
  items of feed only - how do they do that??</p></li>
  <li><p>If you mouse over an item of feed on qapture website, you can see
  other information of that feed item, such as '9 hours ago', '6
  tweet(s)', etc - how do you get that information from?</p></li>
  </ol>
  
  <p>Which area of Twitter API that I should look into to achieve these...?</p>
  
  <p>I'm using PHP and Jquery for my web development by the way...</p>
  
  <p>Many thanks!</p>
