This is a side issue but I'm curious as to what people's reactions are: I'm kind-of hoping that dark matter turns out to be massive neutrinos. Of the various candidates, it seems like the most familiar and comforting. We've even seen neutrinos interact in particle detectors, which is way more than you can say for most of the other alternatives... Compared to axions or supersymmetric particles, or WIMPs, massive neutrinos have have more of the comfort of home. Anyone feel similarly?
As I understand it, there is a known upper bound on neutrino mass that is large enough to allow them to account for some of the dark matter, but too small to allow them to account for all or most of it.
