There are two common podcast aggregators which are free to download, though each politely invites you to make a donation. Press
j to visit the Juice download page, or

If you already have a podcast aggregator, press C on your keyboard, then hold down the control key and press C again. This will copy the podcast u r l to your clipboard. You can then bring up your aggregator and paste the u r l into it's subscription textbox with control V.
