CGTalk Coding form seems like a ghost town.

What kind of coding are you looking to do ? A custom app of your own ? Plugins/scripting for various apps ? For the first, try blender forums, those are very friendly and open about what all you need to learn and the theory behind it. And of course the blender source will really help if you want to see how particular tools/features are put together. For the second, your best bet is the code sections of various app forums. Also renderers often have their own forums if you're interested in coding shaders.

You will also need to buy some good books on CG math and algorithms. Bookmark wolfram mathworld too.

That's really interesting. Any plans to allow custom Cg shaders in the future (if you're allowed to say of course) ?
