title: What is search.twitter.com's "trending topics" algorithm?
body: <p>What algorithm does twitter use to determine the 10 topics that you can see at <a href="http://search.twitter.com" rel="nofollow noreferrer">search.twitter.com</a>? I would like to implement that algorithm and I would also like to show the 50 most popular topics (instead of 10). Can you describe the most efficient algorithm?</p>
  
  <p>Thanks!</p>

  <p>Also, I would like to be able to implement the algorithm by searching through the public timeline- <a href="http://twitter.com/statuses/public_timeline.rss" rel="nofollow noreferrer">http://twitter.com/statuses/public_timeline.rss</a></p>
