I find that if I want tv on in the background while I piddle about the house, I enjoy Google's Current TV. One example is
this amusing installment of Viral Video Film School. On the more serious side, NPR has been broadcasting the World Affairs Council conference at Asilomar for the past few nights. I hope they make it into a podcast, because I missed the first one, and part of the second one. I'm listening to the third part tonight, but this material is worth a second listen.
