title: Twitter Trends by categories
body: <p>Just curious to know that whether there is a way in twitter to check for the popular trends in categories e.g.  'automobile', 'sports', 'forex' etc, just like we have the search.twitter.com providing us with the search for keywords. is there a way we can search for particular trends associated with some category.</p>
  
  <p>Thanks,</p>
