Translating Geek Into English

The question I pose to you is: how much should I charge for the book? There will be a minimum charge (i.e., you cannot pay less than X), but the system will be set to allow readers to pay whatever they want above that. For example, one person has already offered to pay $50 (seriously). And she is the most awesome person in the world. But I’m not going to charge $50. From my perspective, the book is a ton of work, and I have no guarantees of income (especially compared with going the traditional publication route), but I don’t want to gouge readers, either.
