Thanks for listening, and your comments. Sorry about the audio infelicities.

Unfortunately, it seems to be an artifact of some very imperfect recording environments — including the Garden State Parkway and a huge, vacant hall at the headquarters of the Internet Archive (a former church: http://goo.gl/maps/sVBB)

The technology is good enough to get these very smart (and always moving) people together in conversation with the world, but we’ve got a way to go before NPR-quality audio is possible in such conditions.
