From Open Source, about an impending show:

We can’t stop talking about Jonathan Lethem’s essay in this month’s Harper’s. If you haven’t read it, you really should. Nothing that follows in this post will be nearly as interesting. Go ahead. And this post will still be here when you return. You know you want to.

Those of us fascinated by the cultural phenomenon (and the practical process) of mashups and the general subject of repurposing will be especially interested in both the essay and the forthcoming podcast.
