Thanks to Mar Dwi for pointing out that his blog feed was missing from the Art Gallery Consolidated Feed. I tracked it down to some overly-strict XML validation that was silently failing a ton of feeds. I removed some of the restrictions and now everthing is flowing well. Many blogs were being ignored and are now showing up. The feed has a whole new life now! Check it out, and read this post about why it's so important to have a simple blog for your gallery!
