My favorite is still Downcast. I love that it allows me to rank podcasts. I have one playlist sorted by rank and date. I eventually hear everything but the shows I want to hear first (before they go stale or just because I like them more) are always at the top. When I'm done with those, the others are ready to go. And, you can download just one episode or one file (doesn't even have to be an actual podcast—you just need the URL of the media file) at any time. You can easily put podcasts on hold if you don't want to listen for a bit. It's terribly handy. And, no account needed.
