I think there's a bug with how the caching works for podlings.xml, but I'm not sure if it's something I introduced or something I'm just noticing.
I would expect that the cache is comparing podlings.json to podlings.xml. If podlings.json mod time is newer than podlings.xml, read the values from there. Otherwise, refresh from the xml file. Presently, it looks like we're checking the cache folder for the xml file and re-reading that. Thoughts? John
