Since I’m on California time and wide awake, figured I’d add to the great Twitter visualizations posted by @coffee001.  The first visualization shows the relationships between Twitterer/THATCampers coming this weekend.  As this is the third THATCamp at CHNM, I’m not surprised by the density, but you can also see a lot of nodes on the periphery as the network continues to expand. Note that red lines are reciprocal “follows,” blue lines are one-way.

In-network relationships for THATCamp attendees as of May 18, 2010

The second and third visualizations are before and after the Great Lakes THATCamp in March. You can see how the events increase the density of the networks.

I thought I’d try out a few scripts I’ve hacked together on the #thatcamp hashtag to give you a very rough impression of what people have been tweeting prior to the event itself. My collection consists of about 500 tweets that cover the time span from circa the 14th of May up to tonight. Since they’re tagged with #thatcamp, my little corpus also includes conversations from people elsewhere (e.g. THATCamp Paris). I’ll do a similar analysis once the camp is over and hopefully I’ll be able to refine it with ideas from my fellow campers.
