Look for the complicated paradigms that have no simple explanations - things that fascinate you ideally; research them and cut through all the BS, connect the dots for people, explain the consequences and applications of the paradigms and make it simple for people to understand, don't dumb it down necessarily, but explain it in terms that non-genii can understand with real world metaphors that everyone has experience with ... and they will come. At least, I will :P
