Social Network Analysis of Survey Participants
I did a little analysis of our survey participants. The following picture shows the social network between the people who answered our questions. Red nodes are users who retweeted my announcement. The big node in the middle is me (I did not take part in the survey but added me for the network analysis). There is a little bit wrong influence in this analysis because I added some of the participants to my network after the survey because their updates were protected and we needed access or just because they were interesting. You can clearly see that all but two nodes are connected to each other. The survey was promoted 99% via Twitter so this is a logical consequence. The two lonely nodes may come from this posting on the Microblogging Conference blog.
I used a great piece of software called Network Workbench (nwb) for the visualisation. The connection data was retrieved via the Twitter API and imported into nwb as CSV file (one row of the file looks like “usera, userb, true” that means that “usera” is following “userb”).
