I really don't get podcasts. I suppose that since the only thing I listen to on the radio is NPR in the mornings on the way into work, and don't get to listen to music while I'm at work (and rarely do at home), hearing a bunch of guys chat about something in the background from my computer doesn't really curl my toes. That, and I need to turn the sound up if I do, which means all my other applications beep and whistle and make noises constantly.
Part of it may just be that you don't have a long drive to and from work.

In my case, it's a 45-minute drive, and the radio can get real boring real fast. The same old music repeats over and over, and the talk shows tend to repeat topics. So I just download my podcasts into my iPod, and I'm set.
Part of my own love for it undoubtedly springs from my broadcasting background. I've worked at a college NPR station, at a PBS station, and at a couple of UPN/WB affiliates. This sort of stuff interests me.
What I like about podcasting is that you can hear things you can't hear anywhere else. Where else can you get radio shows about science fiction and fantasy? Some of them are extremely well-produced, such as Tracy and Laura Hickman's Dragonhearth podcast, Mike and Evo's Slice of Sci-Fi and Dragon Page podcasts, or The Signal (the Big Damn Serenity Podcast). Some are great tools from fellow writers. Tee Morris and Mur Lafferty have some great podcasts for writers.
Plus, you have things such as Podiobooks.com where you can get podcast versions of novels for free (though you can make a donation). Tracy Hickman is re-releasing
The Immortals as a podiobook. He adds a lot of cool sound effects and does some neat voice characterizations, so that makes it even better.
So for me, I just listen to podcasts on the way to and from work, and over lunch. I've gotten into them so much that I now work as a writer and voice talent on the Signal. I'm having a blast with it.
