For those who use podcasts, Joe Carter highlights what looks to be a helpful tool:
"#420 Podcast Hack -- Podcast search engine PodZinger lets you search podcasts as if they were text files, allowing you to see what’s inside the podcast. When you type in a word or terms, PODZINGER not only finds the relevant podcasts, but also highlights the segment of the audio in which they occurred. By clicking anywhere on the results, the audio will begin to play just where you clicked. There are also controls that let you back up, pause, or forward through the podcast. Or you can download the entire podcast. (HT: LifeHacker)"
