At AB's request, I've done new versions of the WordCloud from tweets during the conference. One includes all retweets and the content is relatively un-curated; in the other two, I stripped out all the retweets, got rid of &, URLs, "th" and "st" after numerals, hash tags, and handles, and expanded "St" to "Saint" (some of these requested by AB). The sites I used were: https://tagul.com/create and http://www.wordclouds.com/
