I love podcasts. I've been listening to them for a couple years now, because I found Skeptics' Guide to the Universe, Skeptoid, and Scientific American. There are so many good podcasts out there, and such a huge diversity. Chariots of Iron, SGU, Skepticality, This American Life, Dan Carlin's Hardcore History, etc etc.
What initially draws you to a podcast- the topic, the slickness of their advertising, their format, the options they have available for their community- and just as importantly what keeps you listening- length, quality, editing, topics, professionalism?
I think that high quality, professional sounding/seeming, podcasts with interesting topics and knowledgeable discussions about those topics are my favorite. I listen, regularly, to several podcasts on the same very broad topics- skepticism, atheism- and I've heard similar interviews in the same week. When the topic is interesting enough, or if the hosts/discussions are interesting enough, even getting the same information a couple times is fine by me. Of course, I always love hearing interesting and different topics; but that's not always gonna happen- like around TAM time.
And if you don't listen to podcasts- why not? Where do you, those of you that do listen, listen at? What activities do you do while listening?
Data! I need DATAS!
