Of the numerous Doug Pratt’s out there, the best known is the Doug Pratt who edits and publishes The DVD Newsletter, which he started as The LaserDisc Newsletter. When I first got on the Net from home, almost fifteen years ago, I was on Usenet a lot, and I posted comments to LaserDisc newsgroups. Because I was very knowledgeable about the format, everybody assumed I was Doug, so I added a disclaimer insisting I wasn’t him.
Doug can be heard in a recent 90-minute conversation on Blog Talk Radio, at this link. Maybe later the host can figure out how to level-match the loudness of the phone calls.
