Continuing the digression on education levels:
I would divide that into:
What reading level are we targetting? We should keep this fairly low - it helps with less-educated readers, English-as-a-second-language readers, and even proficient English readers.
What level of science education are we targetting? I think the sweet-spot level of education should be "finished high-school". Less than that, and we are going to have to give too much background information (defining terms like "atom" and "erosion"). More than that, and we lose too much of our audience.
