Extreme Genes is an entertaining and informative genealogy and family history radio show. There is something for everybody here and I encourage you to check it out.
Here is episode 180 - "Photo Detective Maureen Taylor On Finding Ancestral Photos." There are a few other interesting interviews and commentaries in this episode.
There is also a much appreciated mention of The Psychogenealogist as a genealogy blog to follow. You can here it at around the 6 minute 15 second mark.
