Since I've become more interested in virtual worlds and metaverses (more on these later) I've added some new links. Raph Koster is a gaming genius and offers a lot of interesting ideas about virtual worlds and games on his blog. 3PointD is another blog that focuses on virtual worlds.
Since I work at an agency that tells brands how to get the most out of their sponsorship dollars, and since I read and breathe sports pretty much all day at work, I figured I'd add two of the best blogs I've seen in this space to the blogroll--SportsBiz and The Sports Economist.
Hopefully you will find these links interesting.
