This one is a bit roundabout but stick with me. I've exchanged a few emails with the science.org website technical support people about the RSS feed for the excellent chemistry/pharmacology blog "In the Pipeline". It's not Derek's fault at all, but his science.org/aaas hosts have basically blocked native RSS feed readers and they only allow corporate service websites that do the feed reader part for you like Feedly.org. They consider using a native application feed reader to be scraping their website and ban them.
