I can't do podcasts. I guess that's just because I haven't found anything for me. Audiobooks? Better. Then again, I usually just have stuff on as background noise these days - radio or music when driving, doing housework, running, etc. I don't want anything I really have to focus on, just something to break the silence.
If you're interested in audiobooks check out what you can get through your local library online. You might be surprised...
