The Fourth International Public Knowledge Project Scholarly Publishing Conference was held August 19 – 21, 2013 in Mexico City, Mexico.
I have shared an archive of the tweets tagged with #pkpconf on figshare. I started the archive on Augutst 14 2013 at 15:02:58 GMT and the I closed the last tweet in the archive is from 01 September 2013 at 20:16:39 GMT.
The archive contains 841 tweets. Towards the end of the conference, the backchannel activity peaked at more than 450 tweets.
The tweets per person average was of 5.44, with a tweets per person median of 2.
Here’s hoping the archive is of some use to someone else.
