OPML Reading Lists

As best as my addled morning mind can parse, OPML Reading Lists is simply the idea of subscribing to someone else's (RSS) subscriptions (their "Reading List").  It's just subscribing to the OPML list itself, rather than to individual feeds.  As their set of subscriptions changes, your view is also updated.  Anyway, that's the nugget of knowledge I excavated out of the jargony paragraph

Reading lists are OPML documents that point to RSS feeds, like most of the OPML documents you find, but instead of subscribing to each feed in the document, the reader or aggregator subscribes to the OPML document itself. When the author of the OPML document adds a feed, the aggregator automatically checks that feed in its next scan, and (key point) when a feed is removed, the aggregator no longer checks that feed. THe editor of the OPML file can update all the subscribers by updating the OPML file.

There is a howto of sorts at http://www.reallysimplesyndication.com/howtoReadingLists

You're supposed to keep your reading list small, e.g. 15 items or less, apparently mostly for technical reasons.  But I don't see why we can't fix that with a layer of technology.  I've already got all my 100+ feeds in tidy categories containing most-15-or-less items within Bloglines, why can't it just suck up that, then let the subscriber select which categories they want within the big file?

Now Technorati Favorites would seem ideally created for this, but inexplicably they have not provided OPML export.  You can leave feedback in Sifry's posting New Technorati Features: Favorites. And Reading Lists/OPML for Blog Finder (February 21, 2006).

UPDATE 2006-05-01: Technorati now provides OPML, see Technorati Favorites: RSS and OPML

ENDUPDATE

Thanks to Steven Cohen for pointing out reading lists and for putting me on his.
