Thing 19 Podcasts

I have already looked at podcasts, and made one for a class I took. I couldn't figure out how to get it from my computer onto my blog. Doesn't it have to be online first like our pictures did? I didn't poke around much on any of the sites. Rather, I looked, but I didn't listen to very much. I guess I'm like most of us, I'd rather LOOK at something than just listen to it.
