Podcast Publishing?

Some friends and I decided to fuel our egos by recording some of the fascinating discussions we have over drinks, with the thought of turning it into a podcast for no one in particular to listen to and no plan other than recording a few episodes and then trying to figure out what to do with them at some point.

Several weeks later we have 5 episodes in the can and now we need to publish them, to complete this ego stroking.

Does anyone have a recommendation on where or how to publish a podcast? We're not so concerned at this point with promoting it as much as being able to easily tell someone how to find it if they are already interested in hearing it.
