A couple of days ago, I pointed  NOV 08 2006

A couple of days ago, I pointed to a patent filed by the Flickr folks for the concept of interestingness. I should have poked around a bit more because there's a related patent filed by the Flickr and Josh Schachter of del.icio.us concerning "media object metadata association and ranking". I'm not a big fan of software patents, but even so, I can't see the new, useful, nonobvious invention here. I also find it odd that these patents reference exactly zero prior inventions on which they are based...compare with Larry Page's patent for PageRank.
