The tweets were flying on the Twitter backchannel at the 2011 CCAE/COABE conference in San Francisco, CA, April 17-20.
There were over 800 tweets between the conference dates. I archived them in a single html file. Be patient – it is a very large file and may take a while to load.

How did you archive all the tweets?
After searching in vain for a tool, I went to search.twitter.com and set up an advanced search ( both hastags and limited by date to the conference dates).
I set the page to 50 tweets and downloaded 15 pages. I then hacked the html into one file.
I am sure there is an easier way, but for this one-off it was doable.
Thanks for doing this, Ken and for sharing it with us.
