For the last several conferences, I have shown wordles (word clouds) of the text from general conference, which show the  frequency of use of words (except words like it, the,and and). Frequency of use determines the word size.

Below is a wordle showing an analysis of text from all the talks from the April 2013 general conference. Other styles of this Wordle can be found here, courtesy of Connor Boyack.
