For the section of my book I’m currently writing, I’m looking for examples of contributions to science by amateurs in the Age of the Web. These can be crowd-sourcings, individuals with ideas or data that pushed a science forward, or some category I am not yet considering. (I’ve already briefly noted Make and Maker Faire. I’ve also spent some time in the book on Innocentive and other contests, but if you have a particular good example don’t assume I already know about it!)

I’d be grateful for any ideas or suggestions. Thanks!
