google for import opml for more information on importing the file into your RSS Reader. e.g.: FeedDemon. In NetNewsWire, one must save the OPML file, then save the file, and import then. Unfortunately, Safari does not save the file properly, it insists on adding an .xml extension. So you have to change that. Irritating, but not insurmountable.
It would be nice to be able to import subscriptions “live” from the web.
