I did something similar with books[1], but drawing the words based on their F-score was a brilliant move. I think it gives the viewer much more information than word frequency, and thus is much more appropriate for generating word clouds. I wish I'd thought of it first.<p>[1]: <a href="http://www.korokithakis.net/posts/book-clouds/" rel="nofollow">http://www.korokithakis.net/posts/book-clouds/</a>
