Wish I would have seen this to post it sooner. But, Steven Pinker's the Language Instinct audiobook is on sale for $4.95 until midnight tonight for Audible members. There are a good many things I don't agree with Pinker about (for example, about language being an "instinct" in the technical sense of that word), but I generally find him to be an engaging writer on linguistics and other topics. And, there aren't all that many linguistics audio materials available, though Audible adding the Great Courses has changed that up a bit. But, at that price the Language Instinct is well worth it if you're interested in linguistics to have something to listen to when you're commuting or riding the bus or whatever. Check it out at the link above.
