While I already subscribe to a ton of podcasts, I often find myself wanting to check out an episode or two of shows I don’t normally listen to.
To do this, I use an awesome service named Huffduffer, which is probably most easily described as Instapaper for audio. Hit a bookmarklet while on an webpage for a podcast episode and and it is added to your Huffduffer feed. This system allows users to subscribe to just one feed in their client, and listen to any individual episodes added to their account easily.
This works really well on sites like 5by5’s, but podcasts hosted on Squarespace don’t. If you host your show on Squarespace, you should check out Marco’s post.
