Unfogged discussion
I discuss linguistics in an Unfogged comment thread, where I am graciously tolerated for my foolish, blinkered, and obtuse comments. You, on the other hand, might find them a bit more palatable. I start off trying to establish the inefficiency of linguistic diversity, but then much of the thread is me making the case that the relationship between phonemes and meaning, and phonemes and affect, is arbitrary. Sapir-Whorf is mentioned.
