With the Internet you have tens of thousands of stations and podcast choices.  Soon to be million, undoubtedly.

Realistically, you will never have enough time to listen to everything you snag, record, or podcast download.  In fact, who wants to listen to same thing day in and day out?   Variety and quality, baby! Thus, space is required on your mp3 player for variety and ensuring your experience matches your mood and education level.   So, I wrote Mp3squisher (akronedge.info/mp3squisher) to make your mp3 player hold 3 to 10 times more hours per gig, increase battery life, reduce transfer time, and help alleviate congestion on your harddrive.  Since this is great for streamripping, sharing, and podcasting, and is free.  I am not including it as part of ahkpod.

Ideally, a good mp3 player would mark podcasts and streamrips as read and could wirelessly sync your shrunken podcasts.  But that will never happen.  I have yet to investigate any sync scripts that would be useful, since I have yet to envision the specs.  I just drag and drop every week or two, deleting listened to broadcasts. But email me.
