This Wednesday, the “Podcast Wednesday” post (which I almost forgot all about), presents a service rather than a single podcast series.
If you still haven’t “heard” about it - Yahoo! has a podcast search engine! It is still in beta, but works very well. You can search for podcast episodes or series, or both! Say you want to find a podcast on Nature, or mentioning Nature in an episode. Well, just use “nature” as the keyword you search for.
Take it out for a spin, over at Yahoo! Podcasts right over here.
