If you want to be a god among the RSS crowd, then what’s missing right now is an OPML export/import/sync utility that handles NESTED FOLDERS, which neither IE nor Outlook does.

The app needs to FIRST read the existing folder tree of the RSS feeds to be exported, and build a folder tree on the import side. Then it needs to transfer the feeds as smaller chunks of OPML files — one inside each folder.

Currently, if you carefully organize the RSS feeds in one MS app, then export, the folder tree vanishes, and you wind up trying to put Humpty Dumpty back together again.
