Can you tell me how to find podcast for sunday show on NPR ?

All day sunday I laid around drifting in and out of sleep with the radio on. I remember hearing an awesome on NPR ( same station that interviewer Terry Something is on) show talking about the internet and how stuff you post on line can come back to haunt and that some employers are actually asking for the password to faceboook account. Then the show went from there to talking about peoples behaviors on the internet and websites where people have dialogue back and forth about a webcam of an empty room saying things like "when is someone going to come walking in" ? It was a weird show and perfect for a lazy sunday while I layed there recovering from a hangover but now I can't find the show. I know the person being interviewed had written a book but the only thing I remember in the title of the book is "dinosaur".

The NPR homepage is confusing.......I would guess the show was around midday and a rebroadcast. I looked under different headings such as "Weekend Edition Sunday" and "on point" with Tom Ashbrook. There is a show Called "Privacy and Civil Liberties" but its not the same show and Tom Ashbrook was definately not the host because I listen his shows all the time.
