I just recently finished gathering a complete year of tweets containing the word 'apple' - from Aug 7th, 2008 until Aug 6th, 2009. There were approximately 2.7 million public tweets over that year containing the word. I have used a sample comprised of every 10th tweet of the complete set to create a shaped word cloud showing the words most frequently used. This is a re-creation of a shaped word cloud visualization I did in January that only included tweets from Jan 20-21, 2009.
The dominant words don't seem too surprising. You can click on the words to jump to Twitter Search and see the matching tweets.
