Speaking of this, does anyone know of a good RSS filter? By that I mean a service to which you give a link to an RSS feed and provide certain filters, and they will provide a link to a modified version of the feed that they host themselves.
Awesome, this is exactly what I wanted! By filtering out all the Apple/iPhone/iPad-related crap, I'll probably be able to cut the number of new items from tech blogs in half.
Everyone forgets about postrank.com (formerly aiderss.com) It is actually what I use to filter HN... but who knows, I may switch over to the HN50 or HN100 described above.
