Ask HN: Do you want to learn about game design?

One could easily rename any submission "X" as "Ask HN: Do You Want to Learn About X?" but it'd be a pretty cheap trick.
The reality is that game design is an art, not a science, and in general, like all arts, natural ability separates the good from the best.
That being said, I wouldn't mind following along if I have time, to try and throw wrenches in and be a devil's advocate.
Be careful to avoid this trap.
I see you're organizing the class mostly through your blog. If you find that to be cumbersome, I've created a collaborative learning website that is designed for this kind of group learning. It can add some structure around the class, help people track their progress, and send out emails to students when new stuff happens. It's called Curious Reef http://curiousreef.com/ and it's free to create and take classes.
It's been a long time since I've learned something not involving mathematics. Game balance, game optimization, game physics etc. all involves mathematics. Whereas game design probably has some mathematics laying around, I would suspect it would be much easier to grab than other mathematics in the area.
