Email from reader J.M.:
As I was perusing LL this afternoon, the title of a post you wrote caught my attention: "Metaphors which you are used to seeing in print". I know that the that/which distinction is becoming less and less distinct, but I still thought it was generally practiced in academia (I am not necessarily a proponent of the distinction, but I generally thought it was still preserved). However, in only the past couple of weeks, I have come across several examples of "restrictive which" (in your post title, a textbook for the sociolinguistics class I am teaching (published in 2007), as well as a non-fiction book on spirituality (published 2011)). Can I assume now that it is customary practice to ignore that distinction in published or collegiate writing? I didn't realize the elimination of that distinction had progressed so much from when I was in college (7 years ago).
