Over at the Ancient Hebrew Grammar blog there is a fantastic discussion going on between Robert Holmstedt, John Cook, and Ian Young on the extent to which linguistics can be used to assign relative dates to the composition of biblical texts (H&C–yes, there is a role for linguistics; Young–no, this is the prerogative of text-critics).  It is a really substantive conversation and also contains some humor as well (discussions of how handsome linguists are as well as calling archaeologists “dirt-diggers/shovel bums” and epigraphers “chicken-scratch readers”).
