I think, in general, the LW community often errs by placing too much weight on a maxentropy prior as opposed to letting heuristics or traditions have at least some input. Still, it's probably an overcorrection that comes in handy sometimes; the rest of the world massively overvalues heuristics and tradition, so there are whole areas of possibility-space that get massively underexplored, and LW may as well spend most of its time in those areas.
