Podcasts

I always feel a little weird to just hear someone speaking without any kind of visual link.
Nevertheless, I have subscribed to an evolution podcast from http://www.drzach.net/podcast.htm and am currently listening to "Why do men have nipples?".
I found Podcast Alley an easier site to navigate as there were genres you could choose to skip to.
I think I could continue to use podcasts as a tool to extend my personal knowledge.
