Marketplace for Wednesday, October 3, 2012
When it comes to social media, it's easy to know what your friends like. But what you may not know is that if you click on one of those things, your "friend" might be getting a commission. We wade into the murky waters of recommendations and advertising. Also, the Chinese computer-maker Lenovo is opening a new factory in Whitsett, North Carolina -- hundreds upon hundreds of miles from where most computers are from. Plus we have the latest entry in our Plan B teacher series and visit with our friends over in the world of Freakonomics.
