    After visualizing chat room dialogue earlier this week, I thought it might be neat to try and visualize some Twitter dialogue from the #LAK11 course.  For some reason I thought it would be simple to extract tweets from Twitter for analysis.  It wasn't!  So if you happen to know an easier way please leave a comment.

  • According to an embedded MS Word document found in one of the HBGary emails, it involves creating an army of sockpuppets, with sophisticated "persona management" software that allows a small team of only a few people to appear to be many, while keeping the personas from accidentally cross-contaminating each other. Then, to top it off, the team can actually automate some functions so one persona can appear to be an entire Brooks Brothers riot online.
  • Using the assigned social media accounts we can automate the posting of content that is relevant to the persona.
  •  There are a variety of social media tricks we can use to add a level of realness to all fictitious personas

  • Really? I thought. How do we know if those are real people? Twitter has to be the easiest thing to fake and to automate with retweets and 180 characrer max sentences. To the extent that the propaganda technique known as "Bandwagon" is an effective form of persuasion, which it definitely is, the ability for a few people to infiltrate a blog or social media site and appear to be many people, all taking one position in a debate, all agreeing, for example, that so and so is not credible, or a crook, is an incredibly powerful weapon.
  • I believe there are many people though who will base their judgment on rumors and mob attacks. And for those people, a fake mob can be really effective.
