The most currently release of iPodder (version 1.1) seems to finally have everything in the bag and is very stable. The last release I was running, don’t ask me what version it was, kept crashing Perl on my Mac. Not a good thing.
The current release uses the OPML directory to keep a constantly updated list of links to blogs offering RSS feeds with Podcasts. It also has the ability to pull singular feeds or your whole group as well as showing you the status of the download and the status of the check in progress. Pretty good.
I’d stil like to see something where you could tell it to “not pick things older than 7 days” so you’re not pulling any really old feeds, but, if you’re in the market for any of the podcast software this is the one I’d recommend.
