This gives you a sense of the quality of the community over at App.net.
Diego Basch (@dbasch) was cool enough to generate wordclouds for the top 100 posters on ADN. Here is mine. Excellent community and Diego is just one of the many I have been lucky enough to meet and learn from at App.net.
The ongoing global wordcloud for ADN Global is always at adn.loqix.com so always neat to check-out.
