I think GuiA gave a good response. Psychologically, I think the $1 level is a bad anchor but then you're also missing a lot between the $10-$100 range where I'd suspect most donations would come (by quantity, not $ total).

Also, you're offering a mention in the README as a bonus - which is a good idea. But IMHO you should consider also having a separate DONORS file (or similar) which will list the names of anyone who donated and still be part of the project. Even such a small gesture will help people bond to the project and feel like they're a part of it, beyond the Kickstarter. I bet there are people who would even donate $5 just to get into such a file on what might be a popular project :-) (sad but true!)

My real thinking behind this is because I might be including this in JavaScript Weekly next week. And if I do, I think it would be awesome if people felt motivated enough to throw you some money.
