When I started reviewing podcasts, two and a half years ago, I think I was the only one. There may have been an abandoned blog that contained an insignificant number of reviews, but that was all. By now there are many more, maybe even more than I actually know of. So here is a list of where you can go.
The Podcast Place. A blog that started in December 2008 and tries to review a couple of podcasts per week from all genres.
Daily Podcast Reviews. Is not exactly a daily blog, but every now and then there is a new podcast review. Among the reviewed podcasts are quite a number of the Quick and Dirty series, best known from the podcast Grammar Girl.
DIY Scholar. My favorite among these blogs and a recurring source of inspiration is the Do It Yourself Scholar. She reviews many educational podcasts as well as videos, blogs and other free academic content.
Baxter Wood. The re-education of Baxter Wood is the blog of a 62 year old truck driver who takes on academic podcast series and reports about them without links. But he is quite exact in how to google the content.
Marje's favorite history podcasts. A near complete source for history podcast reviews compiled in a bookmarking tool. Marje helped me discover new history podcasts, but it seems, I have helped Marje as well.
Open Culture. The free culture blog by Dan Colman, associate dean of Stanford, which used to bring more podcast reviews than it does today. These days there are more general culture links and many, many videos.
Edgy Reviews (feed). A weekly podcast that rates a wide variety of podcasts in sets of three.
Podwatch (feed). An Australian podcast review show that has recently been revived.
Historyzine (feed). A history podcast that also reviews history podcasts.
Forgotten Classics (feed). A literature podcast that opens every episode with one or several podcast reviews in various genres.
