Professor Sosis has now collected all the existing interviews here;  he'll be releasing the 25th interview with Peter Singer later today.  Prof. Sosis has worked on this project for three years now, and has been wholly self-funded to date.  But now you can help him out and show your appreciation here (and help cover his costs!).

Prof. Sosis writes:  "Those who give 1$ or more will receive monthly updates on who I am interviewing (I’m interviewing over a dozen extremely interesting people at the moment), and be listed as supporters on the site (if they wish)!"
