<div class="divOutlineItem" style="padding-bottom: 10px;"><span class="spanOutlineText" style="font-family: Georgia; font-size: 18px; line-height: 140%;">A few weeks ago I noticed that my <a href="http://daveriver.scripting.com/">river</a> was filled with <a href="http://www.npr.org/rss/podcast.php?id=13">FreshAir</a> podcasts. Hundreds of them, dating back to 2007. One for every weekday for five years. </span><a name="aFewWeeksAgoINoticedThatMyAHrefhttpdaveriverscriptingcomriveraWasFilledWithAHrefhttpwwwnprorgrsspodcastphpid13freshairaPodcastsHundredsOfThemDatingBackTo2007OneForEveryWeekdayForFiveYears"> </a><a href="#aFewWeeksAgoINoticedThatMyAHrefhttpdaveriverscriptingcomriveraWasFilledWithAHrefhttpwwwnprorgrsspodcastphpid13freshairaPodcastsHundredsOfThemDatingBackTo2007OneForEveryWeekdayForFiveYears"><img src="http://scripting.com/images/2001/09/20/sharpPermaLink3.gif" class="imgBlogpostPermalink" width="6" height="9" border="0" alt="permalink"></a></div>
<div class="divOutlineItem" style="padding-bottom: 10px;"><span class="spanOutlineText" style="font-family: Georgia; font-size: 18px; line-height: 140%;">I figured something glitchy happened, and shrugged it off. Sometimes people adjust their content management system, and the feed guids all change, so the aggregator thinks they're all new. It's a bit more expensive in the case of podcasts because it downloads them all, and it wipes out all the other MP3s in my Podcatcher folder, because it's managed by the software to only use a fixed amount of storage. So every time a new podcast is downloaded, the oldest one is removed.</span><a name="iFiguredSomethingGlitchyHappenedAndShruggedItOffSometimesPeopleAdjustTheirContentManagementSystemAndTheFeedGuidsAllChangeSoTheAggregatorThinksTheyreAllNewItsABitMoreExpensiveInTheCaseOfPodcastsBecauseItDownloadsThemAllAndItWipesOutAllTheOtherMp3sInMyPodcatcherFolderBecauseItsManagedByTheSoftwareToOnlyUseAFixedAmountOfStorageSoEveryTimeANewPodcastIsDownloadedTheOldestOneIsRemoved"> </a><a href="#iFiguredSomethingGlitchyHappenedAndShruggedItOffSometimesPeopleAdjustTheirContentManagementSystemAndTheFeedGuidsAllChangeSoTheAggregatorThinksTheyreAllNewItsABitMoreExpensiveInTheCaseOfPodcastsBecauseItDownloadsThemAllAndItWipesOutAllTheOtherMp3sInMyPodcatcherFolderBecauseItsManagedByTheSoftwareToOnlyUseAFixedAmountOfStorageSoEveryTimeANewPodcastIsDownloadedTheOldestOneIsRemoved"><img src="http://scripting.com/images/2001/09/20/sharpPermaLink3.gif" class="imgBlogpostPermalink" width="6" height="9" border="0" alt="permalink"></a></div>
<div class="divOutlineItem" style="padding-bottom: 10px;"><span class="spanOutlineText" style="font-family: Georgia; font-size: 18px; line-height: 140%;">But then it happened again. And again.

<div class="divOutlineItem" style="padding-bottom: 10px;"><span class="spanOutlineText" style="font-family: Georgia; font-size: 18px; line-height: 140%;">I was busy with another project so I did the simplest quickest thing, I unsubbed. But this meant I had to go to the FreshAir site to <a href="http://www.npr.org/programs/fresh-air/">manually see</a> what's new, because I like to listen to FreshAir on my daily walk.
