Perhaps reaching new depths of geekiness here, but I added a relationship mapping feature to my local gaming Wiki. It shows how nodes link to one another; here’s Reese Beulay as a collection of boxes and lines.
This is actually pretty useful for visualizing how characters relate to one another. I’m going to play around with using it to do relationship maps for new campaigns, too.
There’s probably some clever way to use this to visualize blog connections, but I’m not sure that it wouldn’t just degrade into a black hole. Maybe I’ll play with it sometime.
