I have lots of ideas running around in my head most of the time. The vast majority of them are useless. Very occasionally I come up with something that I need to think more about later, or that needs some refinement. So I post them here.
Also, I'm not terribly impressed by the patent system, so by placing any ideas I've had here, I should stuff up most people's chance of patenting anything resembling these. But I've tried to put together reasonable business models for any business ideas if you want to make something out of them. And if you've got any ideas or contributions, I'd love to hear about them.
