A response from the creator of the two-dollar challenge

Shawn Humphrey, the creator of the two-dollar challenge (and the author of the post I linked to at the start of my entry on it) shared some thoughts on the limitations, but also the strengths, of his campaign. As cecile_c says, pedagogy is a puzzle: how best to reach people? Shawn speaks from experience. His response is here, but for the click averse, I've posted it below as well. Thanks Shawn, for being such a great model of constructive engagement!
