To create this Wordle, I used the results from tweetfeel. The results were positive, with 84% of the tweets being considered positive.

This word cloud was created from the Twitter Sentiment results. The results were positive, but not as much as with tweetfeel. 77% of the tweets were deemed positive. I don't think the ratings tool are related to word count. I think they are much more related to key words in the tweets. Sometimes using key words as the method of rating yields false results. For example, I searched the movie Inglourious Basterds. One of the tweets said, "Inglourious Basterds sucks me in every single time." This was deemed to be a negative response by tweetfeel, presumably because of the word "sucks." However, I think it is clear that this should be considered a positive tweet about the movie.
