Keyword tool for twitter?

Hi guys,

Is there any keyword tool for twitter. I would like to know what keywords were most searched last month, year or week.

Thanks

twitter uses hash tags.. try ritetags.com

I think you'll want to search for popular / trending hashtags, rather than keywords

To find hashtags or keywords searched for, I dunno, does google trends offer an option for twitter only?

The most popular words on twitter doesn't look like much help http://techland.time.com/2009/06/08/the-500-most-frequently-used-words-on-twitter/
