I think we need both rationality and improved writing. This is a crowd that isn't going to put up with entertaining writing that doesn't have significant amounts to say about rationality.

Maybe a good question is "what is the most fun (interpreted very widely) we can have with rationality? I'm not just talking about jokes and entrancing fiction and smiting the unworthy (though those are good things), but looking for emotional intensity, which can be about cracking a problem open as much as anything else.
