I think both your ideas can have a lot of impact. If you start doing data for good competitions or challenges, please notify me, I think there are lots of computer science, industrial engineers and data science student in my area in Germany, that would like to participate in such competitions (at universities in Karlsruhe, Mannheim, Heidelberg and Darmstadt).
@wesg: I really liked your OR post.
