title: How to improve my Algorithm to find the Hot-Topics like twitter does
body: <p>I have created a cron job for my website which runs every 2hours and it counts the words in the feeds and then displays the 10 highest count words as the hot topics.</p>
  <p>Something that Twitter does on their homepage, is to show the most popular topics that are being discussed.</p>
  <p>What my cron job does right now is it counts the words except for the words that i have mentioned, words like:</p>
  <pre><code>array('of', 'a', 'an', 'also', 'besides', 'equally', 'further', 'furthermore', 'in', 'addition', 'moreover', 'too',
                          'after', 'before', 'when', 'while', 'as', 'by', 'the', 'that', 'since', 'until', 'soon', 'once', 'so', 'whenever', 'every', 'first', 'last',
                          'because', 'even', 'though', 'although', 'whereas', 'while', 'if', 'unless', 'only', 'whether', 'or', 'not', 'even',
                          'also', 'besides', 'equally', 'further', 'furthermore', 'addition', 'moreover', 'next', 'too',
                          'likewise', 'moreover', 'however', 'contrary', 'other', 'hand', 'contrast', 'nevertheless', 'brief', 'summary', 'short',
                          'for', 'example', 'for instance', 'fact', 'finally', 'in brief', 'in conclusion', 'in other words', 'in short', 'in summary', 'therefore',
                          'accordingly', 'as a result', 'consequently', 'for this reason', 'afterward', 'in the meantime', 'later', 'meanwhile', 'second', 'earlier', 'finally', 'soon', 'still', 'then', 'third');       //words that are negligible
  </code></pre>
  <p>But this does not completely solve the issue of eliminating all the non-required words. And give only the words that are useful.</p>
  <p>Can someone please guide me on this, and tell me how can I improve my algorithm.</p>
