Were there some Freakonomish economists around, it would be good to find out which peculiar and seemingly unrelated factors correlate with most viewed posts. I'll bet there is some mild correlation between skull size and number of viewers, even if you disregard Lukeprog's posts. Disentangling the variables would be probably unfeasible though.

I wonder about the list of "Would be most visited LessWrong articles if ever written"

Now planning on writing at least two pages per day in 2013... some will end up in LessWrong I suppose. Any LWers with a new years resolution related to LessWrong, or being more rationally productive in general?
