Safari2OPML is a handy utility that can export your Safari RSS feeds to a fairly standard OPML, good for importing into virtually any other RSS reader. I say 'virtually' only because, in my RSS travels, not all readers digest OPMLs alike. Even Safari2OPML's page at FreeSMUG (Free OpenSource Software Mac User Group) lists some of the top readers and whether this OPML will play well with them. For bonus points, Safari2OPML works with Growl to let you know when the export is a success.
Safari2OPML is donationware and available from FreeSMUG.
